摘要

This Note addressed numerical and experimental studies of a pair of rectangular air jets impinging on an inclined surface. Experimental measurements of surface temperatures, using liquid crystals, yielded a map of local heat transfer coefficients between the surface and the incoming jet for an imposed heat flux. Corresponding three-dimensional numerical simulation has been performed using a finite volume algorithm for obtaining detailed temperature and flow distributions. The numerical simulation correlated reasonably well with the experimental results and further explained the flow characteristics and thermal patterns. A detail comparison of 34 locations under the heating pad validated the numerical predictions within 1-3℃ of the measured temperature values. Further investigation should aim for the defogging/defrosting analysis in the flow.
