This paper proposed a new kind of inclined-jet turbine’s structure whi ch the arrangement design was completely finished. Increasing the nozzle number in the structure can enhance the inclined-jet turbine’s output and specific spee d

and the added nozzle will cause the runner interior mobile mutual interferenc e

decrease the unit efficiency

therefore this paper used the CFD technology si mulation the runner interior flowing state in the twin-jet nozzle

analyze the c omputation results between the scoop and jet nozzle’s mutual flowing. Through th e optimization obtains the number of bucket

the best wood pattern line of the i nclined twin-jet turbine and obtained the fluid’velocity

the pressure distribu tion and the fluent path line during in the bucket. The runner interior mutual I nterference situation when the two jet nozzles simultaneously affect the runner. It can provided reference for this new type of inclined-jet turbine’s applicat ion and power plant operation.
