Studying the factors that affects the efficiency of water turbines

Abstract

Our beloved country, Egypt, is drowning in the swamps of problems which are called Egyptian grand challenges that prevent it from entering the race among the developed countries. These grand challenges range from improving uses of alternative energy, arid areas, over population, etc. improving uses of alternative energy is the scoop of this research. There are many types of alternative energy but, this research focus on hydroelectricity especially, water turbines. Water turbines are generating electricity by converting mechanical energy into electricity. In this research, the purpose is studying the factors that effect on the efficiency of water turbines by using the relation between cross-section area and velocity. And also, by using the relation between velocity and power which is cubic relationship and surely the relation between pressure and height. By looking on prior researches trying to know more about hydroelectricity and solving many problems such as water demand and low dissolved oxygen levels in the water. These problems can be solved by using the same idea of the dams but, use sea water which storage in a big tank. And knew about V-shape of the dams or water turbines. Scientific laws and methods have been used trying to increase the efficiency of water turbines. Concluding that increasing the cross-section area in front of blades to increase the pressure on them. And decreasing the cross-section area that distal to the area that in front of the turbine to increase the velocity and increasing electricity power output. The purpose of this research has been achieved and many problems have been solved from prior researches.
