Summary

Heat transfer and fluid flow are fundamental phenomena in nature and engineering. Many aspects in production and daily life are closely related to heat transfer and fluid flow processes. Modeling and simulation of heat transfer and fluid flow are significant for a wide range of scientific and industrial applications at various spatial and temporal scales, with increased interests in recent years. 

Along with the development of computer industry and the advancement of numerical methods, significant advances have been witnessed in modeling and simulation of heat transfer and fluid flow. Solid foundation in both hardware and software has been established to study the processes because of its importance in reducing production costs, discovering new phenomena and developing new technologies, etc. However, accurate modeling and efficient, robust simulation of complex heat transfer and fluid flow still remain challenging. Multi-disciplinary research effort is a clear and general trend for the modeling and simulation of heat transfer and fluid flow, such as 'multi'-modeling, advanced 'multi'-algorithms, heterogeneous parallel computing with 'multi'-hardware, 'multi'-application, etc.

  • Study on a Dual Embedded Discrete Fracture Model for Fluid Flow in Fractured Porous Media
  • Abstract Simulation of fluid flow in the fractured porous media is very important and challenging. Researchers have developed some models for fractured porous media. With the development of related research in recent years, the prospect of embedded discrete fracture model (EDFM) is more and more bright. However, since the size of the fractures in the actual reservoir varies greatly, a very fine grid should be used which leads to a huge burden to the computing resources. To address this challenge, in the present paper, an upscaling based model is proposed. In this model, the flow in large-scale fractures is directly described… More

  • Comparison of Thermal Performance for Two Types of ETFP System under Various Operation Schemes
  • Abstract The earth to fluid pipe (ETFP) system has been widely applied to various energy engineering. The numerical model of the heat transfer process in the ETFP system with a shallow-buried horizontal or a deep-buried vertical U-shape pipe adopted in practical engineering was established and the model distinctions were pointed out. The comparison of the thermal performance between the two types of ETFP system under various schemes was conducted on the basis of numerical prediction. The results showed that the thermal parameters of the ETFP system with a shallow-buried horizontal pipe were influenced by the inlet velocity and ground temperature obviously.… More

  • Study on the Economic Insulation Thickness of the Buried Hot Oil Pipelines Based on Environment Factors
  • Abstract It is important to determine the insulation thickness in the design of the buried hot oil pipelines. The economic thickness of the insulation layer not only meets the needs of the project but also maximizes the investment and environmental benefits. However, as a significant evaluation, the environmental factors haven’t been considered in the previous study. Considering this factor, the mathematical model of economic insulation thickness of the buried hot oil pipelines is built in this paper, which is solved by the golden section method while considering the costs of investment, operation, environment, the time value of money. The environmental cost… More

  • A New Method of Roughness Construction and Analysis of Construct Parameters
  • Abstract In micro-manufacturing, roughness is unavoidable due to the tolerance of micro-machining methods. Roughness in microchannel could have a significant influence on flow and heat transfer since the size of microchannel is very small. In our work, roughness is modeled as a superposition of waves. A simple Fourier series method is proposed to construct the rough surface. With this method, roughness is constructed on the bottom of the rectangular microchannel which has a hydraulic diameter of 0.5 mm. Two important parameters during roughness construction, triangulate size and correlation length are studied under the same relative roughness 1%. Results show that flow… More

  • Modeling Tracer Flow Characteristics in Different Types of Pores: Visualization and Mathematical Modeling
  • Abstract Structure of porous media and fluid distribution in rocks can significantly affect the transport characteristics during the process of microscale tracer flow. To clarify the effect of micro heterogeneity on aqueous tracer transport, this paper demonstrates microscopic experiments at pore level and proposes an improved mathematical model for tracer transport. The visualization results show a faster tracer movement into movable water than it into bound water, and quicker occupancy in flowing pores than in storage pores caused by the difference of tracer velocity. Moreover, the proposed mathematical model includes the effects of bound water and flowing porosity by applying interstitial… More

  • Study on the Variation Rule of Produced Oil Components during CO2 Flooding in Low Permeability Reservoirs
  • Abstract CO2 flooding has been widely studied and applied to improve oil recovery from low permeability reservoirs. Both the experimental results and the oilfield production data indicate that produced oil components (POC) will vary during CO2 flooding in low permeability reservoirs. However, the present researches fail to explain the variation reason and rule. In this study, the physical model of the POC variation during CO2 flooding in low permeability reservoir was established, and the variation reason and rule were defined. To verify the correctness of the physical model, the interaction rule of the oil-CO2 system was studied by related experiments. The… More

  • Numerical Study on the Gas Leakage and Dispersion at the Street Intersection of a Building Group
  • Abstract Accidents involving natural gas leakage and dispersion pose a significant threat to human life and property. This threat is especially relevant at the street intersection at which dense buildings, heavy traffic flow, and complex underground pipe networks meet. Scholars have conducted numerous studies on gas leakage and dispersion, but investigations of natural gas leakage and dispersion at the street intersection of a building group are not in-depth. In this paper, we presented a three-dimensional (3D) physical model based on the Computational Fluid Dynamic (CFD) methodology to study the natural gas leakage and dispersion at the street intersection of a building… More

  • A Staggered Grid Method for Solving Incompressible Flow on Unstructured Meshes
  • Abstract A finite volume method based unstructured grid is presented to solve the two dimensional viscous and incompressible flow. The method is based on the pressure-correction concept and solved by using a semi-staggered grid technique. The computational procedure can handle cells of arbitrary shapes, although solutions presented in this paper were only involved with triangular and quadrilateral cells. The pressure or pressure-correction value was stored on the vertex of cells. The mass conservation equation was discretized on the dual cells surrounding the vertex of primary cells, while the velocity components and other scale variables were saved on the central of primary… More

  • Thermal Modeling and Analysis of Metal Foam Heat Sink with Thermal Equilibrium and Non-Equilibrium Models
  • Abstract In the present study, the thermal performance of metal foam heat sink was numerically investigated by adopting the local thermal non-equilibrium (LTNE) model and local thermal equilibrium (LTE) model. Temperature field distributions and temperature difference field distributions of solid and fluid phases were presented. Detailed thermal performance comparisons based on the LTE and LTNE models were evaluated by considering the effects of the relevant metal foam morphological and channel geometrical parameters. Results indicate that a distinct temperature difference exists between the solid and fluid phases when the LTNE effect is pronounced. The average Nusselt numbers predicted by both the LTE… More

  • Dimensionless Variation of Seepage in Porous Media with Cracks Stimulated by Low-Frequency Vibration
  • Abstract Pulse excitation or vibration stimulation was imposed on the low permeable formation with cracks to enhance the production or injection capacity. During that process, a coupling of wave-induced flow and initial flow in dual-porous media was involved. Researchers had done much work on the rule of wave propagation in fractured porous media, whereas attentions on the variation law of flow in developing low permeable formation with cracks under vibration stimulation were not paid. In this study, the effect of low-frequency vibration on the seepage in dual-porous media was examined for the application of wave stimulation technology in developing reservoirs with… More

  • A Numerical Study on Hydraulic Fracturing Problems via the Proper Generalized Decomposition Method
  • Abstract The hydraulic fracturing is a nonlinear, fluid-solid coupling and transient problem, in most cases it is always time-consuming to simulate this process numerically. In recent years, although many numerical methods were proposed to settle this problem, most of them still require a large amount of computer resources. Thus it is a high demand to develop more effificient numerical approaches to achieve the real-time monitoring of the fracture geometry during the hydraulic fracturing treatment. In this study, a reduced order modeling technique namely Proper Generalized Decomposition (PGD), is applied to accelerate the simulations of the transient, non-linear coupled system of hydraulic… More
