Modeling & Analysis of Kaplan turbine

Abstract

The poor power generation is Sudan during summer is caused by the low levels of water follow thus low water head in dams causing them to stop or lowers their power generation. The Jabal Awlia dam is an example. Small Kaplan turbine is been designed in order to generate 100KW of power from water head 3m, and hydraulic efficiency 0.9. Using in the designing process Solidworks for modeling and Ansys program for the analysis for the stresses, strains, and deformation on three different materials, which are Copper, Structural steel, and Stainless steel. Stainless steel was found to be the most suitable for the design for its high resistance against cavitations and rust, and with yield stress of 250 MPa, The main dimensions of the turbine (the hub, runner blades, and guide vans) were calculated and he therefore the hub diameter of the turbine is found to be 0.19m, the runner diameter is 0.63m, with specific speed 1.42
