Renewable energy is the need of developing countries and cross-flow turbine is a promising means of small scale hydro-power production in locations where available head and discharge is comparatively low. The present work refers to experimental analysis of performance of cross-flow turbine for low head, low discharge sites. The work deals with the key parameters influencing the efficiency of the cross-flow hydraulic turbine which includes outer diameter of runner, breadth of the runner, angle of attack, thickness of water jet, spacing of blades in the runner, radius of blades curvature, number of blades, the blade exit angle for first stage and angle between relative velocity of entering water jet and turbine outer periphery. The variation of efficiency and runner speed with different angle of attack, nozzle tip elevation and nozzle tip distance from runner is analyzed in the present work. The runner consists of 12 blades symmetrically arranged between two circular end plates at the plate periphery. The setup is prepared for the sites where head available is relatively medium or low. The inlet angle β1 of blade is maintained at around 26º to 28º and outlet angle β2 as 90º i.e. outlet is radial. The key parameters such as nozzle inlet angle, nozzle tip elevation and its horizontal distance from center of the runner shaft are varied for different heads as per different site configurations.
