INVESTIGASI PENGARUH KETEBALAN SUDU CEMBUNG LEADING EDGE TURBIN CROSSFLOW SKALA PIKO MENGGUNAKAN METODE CFD
Many villages in Indonesia still face limited access to electricity due to geographical conditions and low income levels. The use of pico-scale crossflow turbines is one of the right alternatives to increase the electrification ratio in remote or rural areas. Crossflow turbines are considered economical, because of their simple design, relatively low installation costs, and have the ability to utilize the potential of water energy with low discharge and head. Optimization of crossflow turbine performance can be done through increasing the lift force on the upper blade configuration with a convex profile on the leading edge. This study aims to analyze the effect of this configuration on the performance of a pico-scale crossflow turbine. The analytical method is used to theoretically design the turbine parameters, while the Computational Fluid Dynamics (CFD) method is used to analyze the fluid flow phenomena occurring around the blades. The results of the study indicate that at a head of 3 meters, a T/L ratio of 0.5 produces maximum efficiency of 79.29% with mechanical power of 186.92 W at a rotational speed of 700 rpm. Meanwhile, a T/L ratio of 1.5 yields the minimum efficiency of 52.40% with a mechanical power of 128.44 W at a rotational speed of 300 rpm. CFD results and ANOVA (Analysis of Variance) calculations show that the blade thickness ratio in the convex leading edge configuration affects the performance of the pico-scale crossflow turbine.
