Title: Numerical Simulation of Flow Velocity Fluid in Nozzle in the Automobile Waste Heat Generation System
Abstract: The finite element method is adopted to numerically simulate the flow velocity fluid in three kinds of nozzles(cone-shaped nozzle,rectified nozzle,variational section nozzle) through the control volume equation.The results indicate that velocity in the outlet is the biggest and backflow is the smallest in conical jet nozzle under the same operating condition,when λ=b/a=0.16.The computed results will have reference value for the waste heat generation system nozzle,especially for the steam turbine nozzle used in Rankine double circulation system with the organic working substance low boiling point.
