The Numerical Simulation of Gas Turbine Inlet-Volute Flow Field

The Numerical Simulation of Gas Turbine Inlet-Volute Flow Field

The structural and aerodynamic performance of the air inlet volute has an important influence on the performance of the gas turbine. On one hand, it requires the airflow flowing through inlet volute as even as possible, in order to reduce the pressure loss, to avoid a decrease in the effective output power and an increase of the fuel consumption rate of the internal combustion engine which indi...

Numerical Simulation of a Confined Swirling Flow in a Model Gas Turbine Combustor

3-D Numerical Simulation of Gas Turbine Combustor

This paper presents a numerical solution for a changing combustor geometry. The effects of the geometric change on the main parameters of the chamber are considered. For this purpose the original geometry and the new one are simulated numerically by a 3-D CFD code and the results are compared. Finally, comments are presented regarding this change. A model is used for turbulence modeling and a...

Investigation into Influence of Inlet Prewhirl on Flow Field of Diagonal Impeller with Exit Guide Volute

By means of setting inlet pre-rotator ,the inlet and exit flow field of the diagonal flow impeller with exit guide volute have been measured with 5 holes probe, in different flow conditions, and in the conditions of positive and negative pre-rotating. The expe1iment results are compared with that of without the pre-rotator.
