The new development of Very Low Head Turbine has been done in this research use the simple civil construction and resulting the economically viable. The recent development of computer-based tools with more efficient algorithms has allowed a substantial improvement in hydraulic turbine design. The definition of an initial geometry capable to assist certain characteristics of turbine performance is a first step for useful numerical turbine analysis. This paper presents an application of the minimum pressure coefficient and free vortex criterions for axial-flow hydraulic turbines cascade geometry design. The criterion was tested for VLH turbine and it was showed that it is suitable to define the initial geometry for machine design. The grid of the simulation domain was generated with GAMBIT grid software package and the results were obtained using the commercial package Navier Stokes 3-D FLUENT flow to analyze the fluid flow through blade runner. Using this procedure, a study was carried out on a small axial-flow turbine, specifically designed to operate in a Very Low Head. Finally, the results are evaluated to hydraulic efficiency prediction of blade runner turbines. The result of simulation has efficiency of 90% and produced the power of 2071 Watt at rotational speed 180 rpm and torque is 219.79 N-m, at the flow rate of 293.15 l/s. The prototype of turbine system was tested in Laboratory by using small channel system that we made it inside the laboratory. The tested result was obtained maximum efficiency of 90% and the power output simulation and experimental has the differential less than 5% at 200 rpm. © February 2011 IJENS.[/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]And experimental,Free vortex design,Minimum pressure coefficient criterion,Numerical simulation,Very low head turbine[/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][/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][/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]
