Project Description:
Proposes to research the feasibility of reducing backpressure on turbines designed with a right angle bend in the outlet by inserting aerodynamic vanes and devices placed inside the exhaust diffuser.
Proposed Outcomes:
§ A larger turbine exhaust scale model and fan system to replace the present 1/8-size model will be fabricated and tested as part of the project. The expected scale factor is1/4 to 1/3.
Anticipated Benefits:
§ Potential to increase gas turbine efficiency by 1% at little additional cost thereby reducing the cost of power from gas turbines.
§ Large potential retrofit market for turbines installations with right angle bends after the exhaust diffuser.
