Abstract

An experimental investigation of the effect of vibration on convection heat transfer from a horizontal cylinder has been performed for the case in which the entire system, both the heated surface and the fluid, are simultaneously subjected to vibration. A 0.032-in-dia horizontal wire served as the heated surface. The ranges of the experimental variables were: temperature difference, 10 to 100 deg F; vibration frequency, 30 to 240 Hz; acceleration amplitude, 1 to 5 g’s. Improvements in heat transfer due to vibration were observed, with the maximum increase being 200 percent. According to dimensional analysis, the Nusselt number depends on five independent parameters. A dimensionless correlation describing the measured heat-transfer data is given.
