Abstract

Abstract

Fully developed laminar flow properties and heat transfer characteristics in equilateral triangle micro-channels were studied. Based on the theory of Navier-Stokes equations, in the case that a steady heat flux was imported into the fluid at one side of the equilateral triangle, the approximate analytical results of velocity and temperature distributions of the fully developed laminar flow within the micro-channel, as well as the friction factor and Nusselt number of the fully developed convevtion, were given through solution of the momentum and energy differential equations. Then the laminar flow and heat transfer within the micro-channel were numerically simulated with the Fluent software to get the corresponding numerical values of velocity, temperature, friction factor and Nusselt number. In comparison, the analytical results fit the numerical ones well to verify the correctness of the presented method.
- equilateral triangle micro-channel,
- Nusselt number,
