An experimental study of turbulent free convection boundary layer in air along a vertical plate using LDV
Abstract
An LDV and a fine thermocouple were used to measure the turbulence characteristics of the free convection boundary layer along a vertical plate with uniform heat generation in air. An equation was derived for the local Nusselt number in the turbulent region. The results showed good agreement with those found in previous experiments for the free convection turbulent boundary layer. With respect to the turbulence quantities directly associated with velocity fluctuations, however, appreciable differences between the present results and earlier work using hot wire sensors were found.
