Abstract
The purpose of this paper is to experimentally investigate the heat transfer of a mixture (free-forced) on a vertical plate under a uniform heat flux with both assisting currents and opposing currents. Heat flux applied to the plate (inversed test design) using number simulation and optimization of thermal element capacities behind the plate has been done. By determining the temperature degree reached to stable temperature degrees and uniform heat fluxes from the plate, heat transfer coefficients we measure by calculation. By performing the relevant experiments and determining dimensionless numbers, Rayleigh, Reynolds and the Grashof show that the results are within the allowable range and the heat transfer flow is mixed convection. Important parameters in flow properties are displayed and analyzed |
