A STUDY OF TURBULENT WAKES IN CONSTANT STREAMWISE PRESSURE GRADIENTS

Two-dimensional turbulent wakes in constant adverse and favorable pressure gradients were studied experimentally. The static and dynamic pressures through the wake were obtained with calibrated Pradtl-type pitot-static probes, and a computer program was written to extract from these data the velocity profiles, displacement thickness, momentum thickness, and the shape factor. This program further provides the turbulent shear coefficient, eddy viscosity, and Prandtl mixing length within the wake. A wind tunnel was designed specifically for this experiment and its construction details are included. (Modified author abstract)
