This paper is aimed at exploring the performance characteristics of a simple reaction hydro turbine for power generation. Using principles of conservation of mass, momentum and energy, the governing equations have been identified for an ideal case of no frictional losses. The paper also describes the conception of a cross-pipe rotor for remote area electricity production. Using the ideal govern...

For the comprehensive characteristics of hydro-turbine, it is generally grasped through full characteristic curve map hydro-turbine obtained from experiment. However, due to factors such as time cost, fund experimental difficulty and safety, results cannot hold onto each working condition hydro-turbine. And for specific conditions unknown conditions, linear interpolation needs be carried out ex...

Hydropower is the largest renewable energy source in the world. However, in the Columbia and Snake River basins, several species of Pacific salmon and steelhead have been listed for protection under the Endangered Species Act due to significant declines of fish population. Dam operators and design engineers are thus faced with the task of making hydroelectric facilities more fish friendly throu...

The TC 60 open flume propeller turbine is an example of a pico-hydro-based fluid engine. potential the can be maximized by paying attention to flow rate. This study aims analyze performance which influenced changes in discharge. method used descriptive analysis method. testing was carried out at CV Cihanjuang Inti Teknik laboratory Cimahi. Turbine begins making 9 discharge ranges from 1.28 litr...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

in the current work, different methods for optimization of turbine blade internal cooling are investigated, to achieve higher cyclic efficiency and output power for a typical gas turbine. a simple two-dimensional model of c3x blade is simulated and validated with available experimental data. the optimization process is performed on this model with two different methods. the first method is a po...
