THEORETICAL PERFORMANCE OF THE HEATED JET PUMP

Abstract

This study was undertaken to determine the optimum performance of the heated jet pump for blowing boundary layer applications. In order to assess the effect of heating the impelling jet stream, it was necessary to develop expressions which define significant parameters. These are presented as dimensionless coefficients which express momentum per unit area, jet air compressor power vs momentum, and jet air heat energy vs momentum. These coefficients are advanced as useful in the study of heated jet pump performance. Constant pressure and constant area ideal mixing processes are analyzed, assuming air to be a perfect compressible non viscous fluid. A parametric study is made by digital computer. The effectiveness of heating the impelling jet air is established and the results present families of heated jet pumps with their optimum performance limits.
