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.
