For the application, Cross Flow Water Turbine (CFWT) is one of the preferred turbine type since it is easy to manufacture and relatively inexpensive compared to other type of low head turbine. However, there is still limited numerical analysis on the influence of Three-Way Nozzle (TWN) and Control Flow Vane Nozzle (CFVN) on the various head operations for a Cross Flow Water Turbine (CFWT). The basic design of TWN and CFVN quite different especially in the nozzle design. The TWN used a fixed nozzle, but CFVN used a controlled nozzle. The variation of discharge angle and head value operation and the design of Nozzle Roof both for The TWN and CFVN are included as design parameters find its best performance. Based on numerical simulation, TWN has wider working range with higher efficiency of head variation than CFVN. In every same head working condition, TWN has faster angular velocity than CFVN. Highest efficiency level as performance result for TWN is on the level of 81.73% generated by the 90° discharge angle with 5 meters head operation even for CFVN is on the level of 87,3 % generated by the 5° degree control flow vane position angle with 30 meters head operation under the 2-D steady state flow CFD simulation.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is supported part from the Research Center of New and Renewable Energy LPPM Bandung Institute of Technology and Research Center for New and Renewable Energy and Conservation Energy, Ministry of Energy and Mineral Resources, Indonesia[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.5046631[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
