Abstract

During the wind tunnel experiment of gas turbine exhaust volute, supported plate should be installed in the import of exhaust volute for the sake of the stability and security, numerical simulations of the flow field with and without supported plate were carried out by using the CFX software, the total pressure loss coefficient distribution and streamline distribution for the two types of flow field were compared and analyzed. Results show that there is no significant effect to the aerodynamic characteristics of the exhaust volute by using supported plate, which could help to order the aerodynamic parameter and flow characteristics of the exhaust volute.
