Abstract:
Theoretical investigations are performed on the developed laminar
convective heat transfer characteristics for incompressible gases flow
through rectangular micropassages with constant wall heat flux.
Mathematical models are proposed for considering the change in thermal
conductivity of gas in the wall – adjacent region from the kinetic
theory. The dimensionless temperature distribution and corresponding
heat transfer characteristics were both simulated numerically, and the
results are compared to other report simulations with brief discussions.
Key words:
