HISTORY OF UTILIZATION OF THE COMPUTATIONAL FLUID DYNAMICS METHOD FOR STUDY PICO HYDRO TYPE CROSS-FLOW

Energy crisis in particular, electricity the isolated rural areas of Indonesia is a very crucial issue that needs to be resolve through electrification . Compared other options, pico hydro cross-flow turbine (CFT) better option provides electrical power for areas. Studies improve CFT performance can undertaken analytically, numerically, experimentally, or combination those methods. However, development computer technology makes numerical simulation studies have become increasingly frequent. This paper describes utilization computational fluid dynamic (CFD) approach method. review has resulted recommended Renormalization Group (RNG) k-ε turbulence model CFD because its absolute relative error lower than standard and transitional Shear Stress Transport (SST). The RNG 3.08%, 3.19%, SST 3.10%. While unsteady approach, six-degrees freedom (6-DoF) are considered more accurate moving mesh. 6-DoF 3.1% mesh 9.5%. Thus, based on review, proposed study.
