SINOPSIS

Conjugated heat transfer in laminar micro-channel flow is analyzed, taking into account the axial diffusion effects which are often of relevance in micro-channels, including pre-heating or cooling of the region upstream of the heat transfer section. The methodology is based on the hybrid numerical-analytical approach known as the Generalized Integral Transform Technique (GIIT), applied to a single domain formulation, which is proposed for modelling the heat transfer phenomena at both the fluid stream and the channel wall regions. By making use of coefficients represented as space dependent functions, with abrupt transitions occurring at the fluid-wall interface, the mathematical model thus carries the information concerning the transition of the two domains, unifying the model into a single domain formulation with variable coefficients. Convergence of the proposed eigenfunction expansions is illustrated and emphasis is placed on the effects of heat transfer to the upstream flow region.
