...Lianfu Dai; Huiying Wu In this work, rarefaction effect, heat transfer, and drag coefficient for gas flow around a square cylinder in transition flow regime are numerically studied using unified gas kinetic scheme (UGKS). To reduce computational cost, a mirror symmetry boundary treatment for UGKS...

... wall temperature boundary, unyield region of temperature-dependent model at rear of circular tube is smaller due to a higher shear rate and lower average viscosity. On the surface of circular tube, local skin drag coefficient first increases and then decreases, and local Nusselt number decreases near...

... the steadiness of the flow field. The Nusselt number can be increased, which leads to a moderate rise in the drag coefficient. Thereby, the effect of the borehole depends on the Reynolds number, the bore diameter, and the angle of attack. For that reason, drag forces and total heat transfers do not simply follow...

... to 3.594 cm for the wing-shaped tubes. Based on the recorded time distributions of velocity u f ( t ) and temperature T f ( t ) , time average Reynolds number Re ¯ , drag coefficient C ¯ d , and Stanton number St ¯ were calculated. In general, the drag coefficient and the Stanton number are smaller...
