Calculating Study of the Turbine at Last Stage Flow Field in the Small Volume Flow Condition

Calculating Study of the Turbine at Last Stage Flow Field in the Small Volume Flow Condition

Based on basic equation and boundary layer theory of pneumodynamics, the thesis conducts numerical modeling and theoretical analysis on the last stage of turbine characteristics at a small volume flow by using FLUENT, gives an emphasized analysis on the position of first occurrence of backflow and i...
