dc.description.abstractNumerical calculation in fluid mechanics "Computational Fluid Dynamics"(CFD) is the news of the "three approaches" in the philosophy of study and the development of all disciplines interested in fluid dynamics; those who studied fluid dynamics in the 1960s still operated with the "two world approaches" which are theory and experience. However, the advent of high-speed computers and the development of precise numerical algorithms to solve physical problems with these computers have revolutionized the numerical resolution of transport equations in fluid mechanics. The aim of this work is therefore to establish a simple calculation model for determining temperatures and heat fluxes on a TPV absorber resulting from the combustion of a characterized biomass (shell of palm nuts) using MATLAB software. A bibliographic review allowed us to describe the different stages in terms of mathematical equations. Taking into account the results of the elementary analysis carried out by Dr Mbakop during his work in 2019, and Dr Epesse during the experimental study, in January 2014 and the literature review; we got the average temperature between 1400 k and 1600 k. We have modeled the flame here under two aspects: firstly, by a radiating cylinder and secondly by a cone whose properties are given by Eurocode1-2. The view factors are calculated by a numerical approach. The evolution of the average absorber temperatures is calculated on the basis of the first thermodynamicsprinciple; and implemented. With regard to the results obtained, we have highlighted the impact of convection and air radiation losses on the radiative fluxes obtained.fr_FR
