Convective heat transfer for incompressible laminar gas flow in micropassage with constant wall temperature

摘要

Theoretical investigations have been performed on the convective heat transfer for incom- pressible laminar flow of gases through microtube and parallel-plates micropassages with constant wall temperature. Considering the change in thermal conductivity and viscosity of gas in wall adjacent region from the kinetic theory, mathematical models are built for both of the micropassages. The dimension- less temperature distribution and the corresponding heat transfer characteristics are simulated numeri- cally, and the results discussed briefly.
