Diagnostics of Constant Area Duct Flow with Induced Turbulence.
Abstract
An experimental three dimensional study was conducted to investigate the effects of grid induced turbulence in a constant area duct of the same relative size as the grids. The duct contained an array of cylindrical rods at the entrance. Various types of turbulence generating grids were placed upstream of the rods to induce turbulence in the flow. The effects downstream of the array were analyzed at three specific mass flow rates. The parameters were used to describe the flow field were the mean velocities, fluctuating velocities, and the Reynolds stresses. Linearized X-probe hot film anemometers were used to measure the parameters. Wall effects were noted.
