Abstract

Mean flow and turbulence intensities have been measured using laser Doppler anemometer for pitched blade downflow turbines (PTD). Fully baffled, flat bottomed cylindrical vessels of 300 and 500 mm internal diameter were employed. The effect of impeller clearance on flow characteristics have been investigated. The influence of geometry of PTD, that is blade angle (30-60°), blade width (0.2D-0.4D) and impeller diameter (0.25T-0.5T) on the flow have been studied in detail. The energy balances have been established around all the impellers and the hydraulic efficiency values have been reported. This part provides a right set of boundary conditions to the model as well as provides necessary and sufficient set of data to evaluate the model performance.
