Abstract
In the present work, the direct and inverse analysis of convective heat transfer with incompressible laminar gas flow in microchannels, within the range of validity of the slip-flow regime, are presented. The direct problem analysis consists in applying the finite difference scheme in the two-dimensional steady-state convection problem. The inverse problem analysis focus on the identification of the momentum and thermal accommodation coefficients, related to gas flow and heat transfer within microchannels, besides the external Biot number, present in the boundary condition. A comparison between the Metropolis-Hastings algorithm and the Monte Carlo Hamiltonian method is made in the solution of the identification problem.
