Thermal balances and complete investigation of air flow along a uniformly heated vertical black thick steel plate (1000 to 8000 W/m²) have been obtained by means of a thermoanemometric method and infrared pyrometry. Several physical models have been solved with a commercial CFD (FLUENT) and the numerical results are compared with the experimental values.
