| Abstract: | In order to conduct aerodynamical design and calculation for a air-coolded turbine,the coolant and gas flow mixing correlations,which satisfied the mass.momentum and energy equations,are derived in rotational coordinates.The computer program has been developed.Calculational results indicate that gas flow parameters change considerably in the case of great coolant mass flow ratio.It is necessary to consider the influence of coolant flow in detail. |
