Numerical Investigation on Effect of Immersed Blade Depth on the Performance of Undershot Water Turbines

Energy, especially electricity, plays a vital role in global social and economic development. High annual rain rate in Malaysia seems a good potential for electricity generation especially through small hydro powers. Undershot water turbines are one of the hydropower turbines used for many years. Ho...
