Abstract
This paper presents a solution obtained through of the Generalized Integral Transform Technique, to the problem of thermal entrance in forced convection in laminar flow inside microtubes of circular section. The model considers the effect of the slip flow, and viscous dissipation. The Generalized Integral Transform Technique is employed to reduce the original problem to a system of linear first-order differential equations, which is then solved utilizing available algorithms for the numerical solution of ordinary differential systems. Results are then presented for the fluid bulk temperature and local Nusselt number along the channel. Critical comparisons with previous results in the literature are also performed, in order to validate the present work, and to demonstrate the consistency of the final results.
