Abstract:

As bases for studies in the design of compressors and turbines and for turbulent flow in magnetohydrodynamic channels, basic numerical and experimental investigations were made towards developing an operational three-dimensional treatment of turbulent transport processes, with consideration of fluid property variation and body forces. Two-dimensional numerical programs were developed and applied for gaseous, internal, turbulent, boundary layer flow in circular tubes and wide rectangular ducts. Measurements under strong heating were a heat transfer and friction parameters for flow through square ducts, b wall temperatures for mixed convection in the laminarization region in circular tubes, c velocity and temperature profiles in a wide rectangular duct, and d velocity and temperature profiles in laminarizing flow in a circular tube.
