Heat straight microchannels

Campo, A. Low Reynolds number flow inside straight microchannels with irregular cross sections, J. Heat Mass Transfer 36, (2000) 187-193. 

If we consider a steady-state, laminar, constant property (i.e., dynamic viscosity p, specific heat Cp, thermal conductivity k) flow in a straight microchannel of constant cross-sectional area (see Fig. 1), in the absence of free convection, mass diffusion, and change of phase, the governing equations can be written as follows ...
