Perencanaan Turbin Cross Flow
Abstract: Nowadays between
sustainablen developments of renewable sources of energy the hydro energy plays
and important and crucial role. Because usually the great hydropower plants
arealready built it remains to harness the medium and small hydropower sources.
Among the different types of hydraulic turbines, the cross-flow type is a real
option and viable solution from technical-economical point of view. The
cross-flow turbines (CFT) consist from two main hydrodynamic machine elements
namely the runner and the nozzle. The CFT is in almost all regimes of operation
an impulse wheel machine. CFT has the peculiarity that, like the pelton
hydraulic turbine, there is no connection between the rate of flow of the
hydraulic turbine and the rotational speed of the runner but the width of the
runner is a function of the rate of flow throught the CFT. In operation the
runner is only partially immersed in water, every inter-blade channel, twice in
a complete rotation of the runner.
