چکیده انگلیسی
Convective heat transfer in a rectangular microchannel under slip flow and H1 boundary condition is studied. Integral transform method is applied to derive the velocity and temperature distributions and thus the average Nusselt number. It is found that rarefaction has a decreasing effect on heat transfer for most engineering microchannel applications, with any aspect ratios. However, an increase in heat transfer with rarefaction is investigated when the influence of temperature jump on solid boundaries is weak. It is also found that the effect of wall temperature on the heat transfer is negligible. The results of paper for the special case of non-slip flow coincide with the results of previous studies.
