Description
<p>This paper presents the accuracy improvement of CFD analysis of turbulent flow around High-Lift Devices (HLD) using Hierarchical Cartesian Mesh, which is combined with Immersed Boundary Method, Wall Function, and Adaptive Mesh Refinement (AMR). When analyzing flow around HLD under high lift condition, the flow is deflected largely and the region away from the HLD should be also resolved sufficiently. However, Hierarchical Cartesian Mesh tends to be coarse in that region. To solve this problem, AMR based on flow field variables is introduced. First, implemented AMR method is validated, and it is shown that flow features such as shock wave or wake region can be detected automatically. Then, AMR is applied to the CFD analysis of HLD using Hierarchical Cartesian Mesh. As a result, the wake region is highly resolved, and the accuracy of the analysis especially at high angle-of-attack is improved. </p>
