Experimental performance investigation of modified split reaction water turbine

In this paper experimental performance characteristics of modified split reaction water turbine (srt) have been discussed and compared with the old srt. the spilt reaction water turbine has shown good potential to be used for low head micro hydro-electric installations. the main advantage of this turbine is its simplicity to manufacture and reasonable energy conversion efficiency of about 65-70% (hydro to mechanical energy). previous findings have shown that the exit water jet tends to separate while leaving the exit nozzle of original turbine design srt-1and hence does not leave tangent to the turbine diameter. in this paper a solution has been proposed to improve this situation and create a more uniform and solid water jet at the turbine exit. computational fluid dynamic simulation has been used to study the internal flow in both the turbine designs. experimental test results have shown that the new design (srt-2) has proved to be useful for creating a solid water jet at exit,and hence the srt-2 design has shown to be more efficient as compared to the srt-1.
