| Abstract: | The mathematical method for optimum design of flow type is developed on the basis of the Turbomachinery Euler Equation and classical variational principle. The fan of 6102 gas engine is optimized by the use of this method. The results are contrased with those of iso reaction coefficiency flow type and free votex flow type. |
