✦ Synopsis

The temperature, velocity, and concentration distributions were measured in boundary layers adjacent to heated vertical polymethyl methacrylate (PMMA) and wood (Southern Pine) surfaces, and next to a heated, vertical, sintered bronze plate through which propane was injected. The temperature, velocity, and concentration were measured as functions of position and time using thermocouple probes, flow visualization techniques, and heterodyne holographic interferometry, respectively. The measured distributions were compared to the results of a simple model. The agreement between the measured values and the results of the model was generally good and was within the experimental uncertainty.
