Proc. ASME. MNHMT2019, ASME 2019 6th International Conference on Micro/Nanoscale Heat and Mass Transfer, V001T10A007, July 8–10, 2019
Publisher: American Society of Mechanical Engineers
Paper No: MNHMT2019-4232
... Abstract A high-order moment method is employed to study the effect of the wall temperature on gas flow past a stationary circular cylinder in terms of the size of the vortices behind the cylinder and the drag coefficient. When the wall temperature is lower than the free stream temperature...

... is less than 0.3, and the drag coefficient of the cylinder increases when the Reynolds number decreases. The compressible effect will increase the pressure drag coefficient although the friction coefficient remains nearly unchanged. The rarefied gas effect will reduce both the friction and pressure drag...
