Summary

Manufacturing is not only the foundation of national economic growth and productivity, but also an important support for building development strategic advantages. Interpreting, describing, predicting and simulating changes in various behaviors and characteristics during manufacturing and material processing is the key to optimizing product attributes. With the development of Industry 4.0 and smart technology, intelligent manufacturing has gradually become an effective means of efficient production. However, even on the basis of smart technology, many physical phenomena will occur in the manufacturing process, such as heat transfer, fluid dynamics, solid mechanics, changes in material state and performance, internal stress, phase transitions, and structural changes, etc. This makes the computational and numerical simulation of manufacturing and material processing very challenging.

Therefore, this special issue aims to publish new and novel original research related to intelligent manufacturing and all classes of material processing. The focus is on the research of computational mechanics, numerical simulation, modeling and fluid dynamics in the manufacturing and material processing processes.

The topics of interest include but are not limited to:

• Finite element and finite-element-based methods

• Numerical methods of structural mechanics analysis

• Molecular dynamics simulations

• Molecular mechanics modelling

• Advanced numerical technology of manufacturing and materials

Abstract This study aims to improve the performances of the high-pressure water descaling technology used in steel hot rolling processes. In particular, a 2050 mm hot rolling line is considered, and the problem is investigated by means of a fluid–structure interaction (FSI) method by which the descaling effect produced by rolling coils with different section sizes is examined. Assuming a flat fan-shaped nozzle at the entrance of the R1R2 roughing mill, the out- flow field characteristics and the velocity distribution curve on the strike line (at a target distance of 30–120 mm) are determined. It is More >

Abstract A hill can be regarded as an environmental carrier of heat. Water, rocks and the internal moisture naturally present in such environment constitute a natural heat accumulator. In the present study, the heat and moisture transfer characteristics in a representative hill cave have been simulated via a method relying on the Darcy’s law. The simulations have been conducted for both steady and unsteady conditions to discern the influence of permeability and geometric parameters on the thermal and moisture transfer processes. The reliability of the simulation has been verified through comparison of the numerical results with More >

Abstract When aluminum alloys are coupled with dissimilar materials, they often act as corrosion anodes and are suscepted to accelerated corrosion. Therefore, deepening our knowledge of such corrosion phenomena, related mechanisms, and elaborating new prediction model is of great theoretical and practical significance. In this paper, such mechanisms are explained from both macroscopic and microscopic points of view by considering several aspects such as the second phase particle type, grain size, and environmental ions. More specifically, different perspectives on such a problem are elaborated, which take into account: the properties of the coupling pair materials, geometrical… More >

Abstract In order to ensure the safe operation of the compressors used in water chillers, in the present study some interlock protections have been added to the related design. These include a low pressure protection, a high pressure protection, an exhaust temperature protection and a differential pressure protection. Some tests have been conducted by tuning the saturation suction and exhaust temperatures of the compressor through adjustment of the cold source outlet temperature and the ambient temperature. The results show that the ambient temperature increases with decreasing device load and increasing fan speed under the same saturated More >

Abstract In order to improve the efficiency as well the adaptability and operability of traditional devices used to dredge drainage pipelines a new design is presented here, obtained by matching the structural specifications of a drainage pipeline with the working principle of a high-pressure water jet (HPWJ). To effectively improve the water jet nozzle performances, the nozzle’s structural parameters of the proposed device have been analyzed through Computational fluid dynamics (CFD) simulation. The corresponding behavior of the fluids inside and outside the self-rotational nozzle has been numerically simulated. The final design for the nozzle has been More >

Abstract The internal temperature of cast-in-place concrete bridges undergoes strong variations during the construction as a result of environmental factors. In order to determine precisely such variations, the present study relies on the finite element method, used to model the bridge box girder section and simulate the internal temperature distribution during construction. The numerical results display good agreement with measured temperature values. It is shown that when the external temperature is higher, and the internal and external temperature difference is relatively small, the deviation of the fitting line from existing specifications (Chinese specification, American specification, New More >

Abstract Gases containing sulfur oxides can cause corrosion and failure of bellows used as furnace blowers in high-temperature environments. In order to mitigate this issue, the behavior of an effective blast furnace blower has been examined in detail. Firstly, the Sereda corrosion model has been introduced to simulate the corrosion rate of the related bellows taking into account the effects of temperature and SO₂ gas; such results have been compared with effective measurements; then, the average gas velocity in the pipeline and the von Mises stress distribution of the inner draft tube have been analyzed using a More >

FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.6, pp. 1411-1424, 2023, DOI:10.32604/fdmp.2023.024924
（This article belongs to the Special Issue: Computational Mechanics and Fluid Dynamics in Intelligent Manufacturing and Material Processing)
Abstract The thermal transmission coefficient for a micro-ribbed tube has been determined using theoretical relationships and the outcomes of such calculations have been compared with experiments conducted using a R1234yf refrigerant undergoing condensation. In particular four theoretical single-phase flow and three multi-phase flow models have been used in this regard. The experimental results show that: the Oliver et al. criterion equation overestimates the experimental results as its accuracy is significantly affected by the specific conditions realized inside micro-fin tubes; the Miyara et al. criterion equation prediction error is less than 15%; the Cavallini et al. approach More >

Abstract A two-layer implicit difference scheme is employed in the present study to determine the temperature distribution in an asphalt pavement. The calculation of each layer only needs four iterations to achieve convergence. Furthermore, in order to improve the calculation accuracy a swarm intelligence optimization algorithm is also exploited to inversely analyze the laws by which the thermal physical parameters of the asphalt pavement materials change with temperature. Using the basic cuckoo and the gray wolf algorithms, an adaptive hybrid optimization algorithm is obtained and used to determine the relationship between the thermal diffusivity of two More >

Abstract To improve the application of discrete element models (DEM) to the design of agricultural crushers, in this study a new highly accurate model is elaborated. The model takes into account the fiber structure, porous nature of the material and the leaf sheath coating structure. Dedicated experimental tests are conducted to determine the required “intrinsic” and basic contact parameters of the considered banana straw materials. A large number of bonding parameters are examined in relation to the particle aggregation model in order to characterize different actual banana straws.

Abstract The design of hydro-bulge molds, able to provide hollow parts with special-shaped cross-sections, is still a pretty complicated task (especially for what concerns the design of the related hydraulic system and its “synchronization”). In the present work, this task is addressed through the introduction of a new type of overhead cylinder hydraulic synchronization system, able to correct automatically any deviation from the optimal process. Using the AMESim software, the displacement synchronization curve of the piston rods of the two cylinders is obtained and it is verified that the system is able to implement an automatic More >
