Abstract
The paper describes the design of a new blowdown wind tunnel carried out at the von Karman Institute for Fluid Dynamics. The work has been driven by the interest to investigate an air/oil integrated surface heat exchanger placed at the inner wall of the secondary duct of a turbofan. The test section consists of a complex 3D geometry to simulate the real bypass flow conditions in the vicinity of the separator nose downstream of the inlet fan. Numerical flow analysis have been used to guide the design of the complete wind tunnel in particular for the design of the test section. Research on this new wind tunnel will be focused on the aerothermal effects of an Air Cooled Oil Cooler surface heat exchanger. The investigated heat exchangers would satisfy needs for cooling the oil circuit while minimizing the disturbance of the air stream. Hence, the objective is to allow maximum heat release causing a minimum loss of the global engine efficiency.
