Abstract
Effects of wall temperature on mass flux and flow field structure in a circular micro-channel are investigated in this paper. It is revealed that the wall temperature affects the mass flux of pressure-driven flow by the viscosity. The simplified relationship between the wall temperature and the micro-tube mass flux is proposed for pressure-driven low-speed flow. However, for high-speed incoming flow, the wall temperature affects the micro-tube mass flux by changing the half-region viscosity. Overall, the effect of wall temperature on the mass flux for low-speed pressure-driven flow is greater than that for high-speed incoming flow.
