Abstract:

This SBIR Phase I project proposes to develop an accurate viscous CFD algorithm which can include various small gaps between both static and moving components into the analysis. It is not an easy task to model those small gaps in the current CFD codes due to the geometric proximity, especially for moving components. However, those small gaps may have a significant impact on the aerodynamic, aeroelastic and thereby flight performance of the vehicle. Therefore, this SBIR effort will try to develop an innovative non-deforming mesh approach to handle this type of problems. In Phase I, a simplified model problem is used to demonstrate the feasibility of using the proposed approach for handling the small gaps between both static and moving components. Therefore, it is meaningful to further extend the approach to the complete air vehicle configuration in Phase II. BENEFITS: The developed CFD algorithm can handle very complicated geometry including the geometric proximity between both static and dynamic components. Therefore, aerospace engineers can use the algorithm to analyze the aerodynamic, aeroelastic, and flight performance of air vehicles, reducing the required wind tunnel tests and flight tests; mechanical engineers can use the algorithm to simulate the flows inside various machinery; etc.
