Abstract

The energy used currently is predominantly fossil energy. Water is a natural resources that can be used as alternative energy to replace the use of fossil fuels. Therefore, the development of water energy as an alternative energy source continues to be improved as well as independent power generation. Crossflow turbines are considered from a number of characteristics such as simple turbine construction, portability and fabrication cost. Previous research recommended the upper blade of a crossflow turbine in the center is better than a blade with an upper curvature. Re-configuration of the crossflow turbine upper blades was deemed appropriate to improve its efficiency. The configuration of crossflow turbine blade upper convex location at the trailing edge is considered relevant to increase the lift. Therefore, this study aims to examine the effect of convex crossflow turbine upper blades at the trailing edge in increasing mechanical power and efficiency compared to curvature upper blades. In this study, the design of the crossflow turbine uses a velocity triangle approach and the number and shape of the crossflow turbine blades are varied into curvature 22, trailing edge 22, curvature 26 and trailing edge 26. Furthermore, 2D simulations are carried out using ANSYS FLUENT 18.1 to determine the effect of number and shape of the blades on the crossflow turbine. From the simulation results, the crossflow turbine with trailing edge shape with the number of 26 blades has a mechanical power output of 367.6 Watt and has an efficiency of 68.3%.
