Abstract

Conjugate heat transfer in rectangular, trapezoidal and rectangular-trapezoidal combined microchannels is investigated for hydro-dynamically fully developed, single-phase, laminar flow with no-slip conditions. Hydraulic diameter of all geometries is so adjusted so that for given aspect ratio of the rectangular microchannel the other two geometries have same hydraulic diameter. Various physical quantities heat transfer coefficient, Temperature gradient has been examined to deduce the effective cooling in the microchannel. Simulation has also been done for various velocities to have a look on effectiveness of the microchannel.
