Caractérisation des transferts thermiques conjugués dans un minicanal par inversion de trames thermographiques

Abstract : A semi-analytical model allowing the simulation of heat transfer in the mini-channel rectangle subjected to the heat source over the external faces, has been presented. This model takes into account the conduction conjugate-advection in the fluid, on another hand the conduction conjugate in the solid. The model developed is based on the Fourier transformer of the temperature and the flux which have been formed into the matrix (quadruple model). The main advantage of this type of model is that can be able to calculate the bulk temperature without using the notions of the heat transfer coefficient, leading us to avoid the assuming added value of this coefficient. However, the main objective of this work is to estimate the internal conditions based on the experimental measurements as well as the initial model. Notice that the experimental measurements of temperature field at different velocities, has been applied on the external faces by using inferred camera (known as non-intrusive method). Those estimations considered done by two different techniques (TSVS and ILSVD).
