Résumé

Measurements of laminar mixed convection flow adjacent to an inclined heated flat plate with uniform wall heat flux are reported. Laser-doppler velocimeter and cold wire anemometer were used to measure simultaneously the velocity and temperature distributions, respectively. Measurements of the air velocity and temperature distributions are presented. It was found that both the mixed convection local Nusselt number and local friction coefficient increase as the buoyancy force increases (under the buoyancy assisting condition). The velocity field was found to be more sensitive to the buoyancy force than the thermal field. Predictions from both local similarity and local nonsimilarity models agree well with the experimental results for the thermal field, but only the predictions from the local nonsimilarity model agree favourably with the measured values for the flow field.
