Numerical Modeling Techniques for Jet Engine Test Cell Aerodynamics
This SAE Aerospace Information Report (AIR) has been written for individuals associated with ground level testing of turbofan and turbojet engines, and particularly for those who might be interested in investigating steady-state performance characteristics of a new test cell design or of proposed modifications to an existing test cell by means of numerical modeling and simulation. It is not the intent of this standard to provide specific test cell design recommendations, which are covered in the reference documentation.
As a complement to AIR4827, this document presents best practices in the domain of numerical aerodynamic analysis tools for determining enclosed test cell aerodynamic performance. Correlated and compared to experimental systems, numerical tools represent an ideal way to reinforce the confidence in predicted performance while allowing for more cost effective and timely aerodynamic analysis.
