Dr. Zhigang Fang, Wuhan University of Technology, China


This special issue is devoted to the discussion of recent developments and applications of EFD 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) Postprocessing and model validation, including Statistical Learning and Uncertainty Quantification;
5) Fluid theory method, such as Navier-Stokes equations. 

EFD, Heat Transfer, Thermodynamics, Combustion, Aerodynamics.

  • Large Eddy Simulation of Gasoline-Air Mixture Explosion in Long Duct with Branch Structure
  • Abstract Gas explosion is a process involving complex hydrodynamics and chemical reactions. In order to investigate the interaction between the flame behavior and the dynamic overpressure resulting from the explosion of a premixed gasoline-air mixture in a confined space, a large eddy simulation (LES) strategy coupled with sub-grid combustion model has been implemented. The considered confined space consists of a long duct and four branches symmetrically distributed on both sides of the long duct. Comparisons between the simulated and experimental results have been considered with regard to the flame structure, flame speed and overpressure characteristics. It is shown that the explosion… More

  • Simulation of the Thermal Environment and Velocity Distribution in a Lecture Hall
  • Abstract The rational design of heating ventilation and air conditioning systems is an important means to achieve energy conservation and sustainable development. The simulation of air-conditioning systems with finite element methods has gradually become an important auxiliary means of complex airspace design. In this paper, a k-ε turbulence model is used to conduct 3D simulations and optimize the summer air conditioning system of a lecture hall. Various conditions are considered in terms of fresh air temperature and flow rate towards the end to improve comfort. The approach used in this paper could also be used in the future as an auxiliary… More

  • RANS Simulation for the Maneuvering and Control of a Suboff Submarine Model
  • Abstract Submarine maneuverability has been analyzed by means of computational fluid dynamics (CFD). This approach provides an alternative, accurate, and cost-effective method for simulating actual flow. The numerical results show that the numerical simulation of the viscous flow related to a moving submarine based on the RANS equation with a relevant turbulence model can not only provide rich flow field details such as flow separation, but also accurately predict its hydrodynamic performance. The present study indicates that CFD can be used to forecast the submarine’s maneuverability in the initial design stage. The present results will be used in the future as… More
