Abstract:

An interferometer study of the effect of reduced pressure on free convection from a vertical plate is presented. The interferometer was used to visually observe the boundary layer on the plate and to determine the heat transfer coefficient over a range of pressure from 0.987 to 0.09 atm. The free-convective heat transfer coefficient was experimentally found to be proportional to the 0.47 power of the pressure which is within experimental limits of the theoretical prediction 0.50 power of the pressure. The boundary layer thickness was observed to increase as the pressure was reduced. Author
