Summary

Fluid machinery is an umbrella term used to describe all machines that convert energy with the help of a fluid. Such machines are often a key component in various fields. The related aerodynamic/fluid-dynamic behavior and performances are closely related to fluid/structure or fluid/material interaction mechanisms. Analysis and optimization of these aspects can therefore improve the performances of these systems, guide material selection and/or component shape definition, thereby enhancing the efficiency and stability of many systems of practical interest. Along these lines, this Special Issue is intended for the presentation of new ideas in the field of aerodynamic analysis and optimal design related to fluid machinery. Relevant systems include (but are not limited to) valves, steam turbines, gas turbines, aviation engines, rocket engines, compressors, intake ducts, wind blades, aerocrafts, helicopters, automobiles, fans, ventilators, and etc. The submitted papers are expected to display original analytical, numerical, or experimental results and physical interpretation of lasting scientific value.

 

The Special Issue is intended for, but not limited to, the following topics:

Aerodynamic analysis;

Acoustics;

Acoustic signal processing;

Fluid dynamics;

Turbulence flow;

Microfluid flow;

Compressible flow;

Computational Fluid Dynamics;

Materials and structures;

Signal and image processing;

Data fusion;

Complex system engineering;

Other fundamental/applied fluid mechanical phenomena and processes.

 

In all cases, the submitted paper is expected to provide indications or recommendations for the selection of relevant materials and/or component shape definition.

    Abstract The quality of crushing, power consumption, and discharging performance of a straw crusher are greatly influenced by the characteristics of its internal flow field. To enhance the straw crusher’s flow field properties and improve the efficiency with which crushed material is discharged, first, the main structural parameters influencing the air flow in the crusher are discussed. Then, the coupled gas-solid flow field in the straw crusher is numerically calculated through solution of the Navier-Stokes equations and application of the discrete element method (DEM). Finally, the discharge performance index of the crusher is examined through detailed More >

    Study on the Relationship between Structural Aspects and Aerodynamic Characteristics of Archimedes Spiral Wind Turbines

    Yuanjun Dai, Zetao Deng, Baohua Li, Lei Zhong, Jianping Wang
    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.7, pp. 1517-1537, 2024, DOI:10.32604/fdmp.2024.046828

    Abstract A combined experimental and numerical research study is conducted to investigate the complex relationship between the structure and the aerodynamic performances of an Archimedes spiral wind turbine (ASWT). Two ASWTs are considered, a prototypical version and an improved version. It is shown that the latter achieves the best aerodynamic performance when the spread angles at the three sets of blades are α = 30°, α = 55°, α = 60°, respectively and the blade thickness is 4 mm. For a velocity V = 10 m/s, a tip speed ratio (TSR) = 1.58 and 2, the maximum C values More >
