Summary

This special issue is devoted to the discussion of recent developments and applications of engineering fluid mechanics and heat transfer.

 

Fluid mechanics is a discipline based on potential flow equations, Euler equations, and Navier-Stokes equations, the development of computer provides theoretical and experimental verification basis for engineering fluid mechanics, and EFD is widely used in the design of aircraft and fluid machinery. Heat transfer studies the transmission patterns of heat energy caused by temperature difference. As theoretical and experimental research continue to close its gaps with production and life, microscale heat transfer, phase change of biological heat transfer, multiphase flow heat transfer, low-temperature heat transfer, and many other interdisciplinary studies and subdisciplines were derived therefrom.

 

In recent years, with the development of micromachining and the growing demand for miniaturization of industrial products, microscale heat transfer has become a hot topic in the research of engineering thermophysics. Related professional experts, researchers, graduate students are welcome to join us in the following topics:

 

1) Aerodynamics, such as aircraft wing design, automotive body design;

2) Fluid-solid coupling analysis;

3) Thermodynamics and heat transfer, such as thermal analysis during engine combustion;

4) Fluid theory method, such as Navier-Stokes equations;

5) Postprocessing and model validation, including Statistical Learning and Uncertainty Quantification.

    Numerical Simulation of the Influence of Water Flow on the Piers of a Bridge for Different Incidence Angles

    Danqing Huang
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.3, pp. 845-854, 2023, DOI:10.32604/fdmp.2022.020314

    Abstract A two-dimensional mathematical model is used to simulate the influence of water flow on the piers of a bridge for different incidence angles. In particular, a finite volume method is used to discretize the Navier-Stokes control equations and calculate the circumferential pressure coefficient distribution on the bridge piers’ surface. The results show that the deflection of the flow is non-monotonic. It first increases and then decreases with an increase in the skew angle. More >

    Analysis of the Thermal Performance of External Insulation in Prefabricated Buildings Using Computational Fluid Dynamics

    Ang Wang, Hui Wang
    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.5, pp. 1293-1306, 2022, DOI:10.32604/fdmp.2022.018561

    Abstract This paper investigates the thermal performance of prefabricated exterior walls using the Computational Fluid Dynamics method to reduce energy consumption. The thermal performance of the prefabricated exterior wall was numerically simulated using the software ANSYS Fluent. The composite wall containing the cavity is taken as the research object in this paper after analysis. The simulation suggests that when the cavity thickness is 20 mm and 30 mm, the heat transfer coefficient of the air-sandwich wall is 1.3 and 1.29, respectively. Therefore, the optimal width of the cavity is 20 mm, and the most suitable material is the aerated concrete block.… More >

    A Mathematical Model of Heat Transfer in Problems of Pipeline Plugging Agent Freezing Induced by Liquid Nitrogen

    Yafei Li, Yanjun Liu
    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.3, pp. 775-788, 2022, DOI:10.32604/fdmp.2022.019810

    Abstract A mathematical model for one-dimensional heat transfer in pipelines undergoing freezing induced by liquid nitrogen is elaborated. The basic premise of this technology is that the content within a pipeline is frozen to form a plug or two plugs at a position upstream and downstream from a location where work a modification or a repair must be executed. Based on the variable separation method, the present model aims to solve the related coupled heat conduction and moving-boundary phase change problem. An experiment with a 219 mm long pipe, where water was taken as the plugging agent, is presented to demonstrate… More >
