    Verification and possible applications of new 3D panel method with boundary layer

  • Original language description

    Robust and well tested 3D panel method for potential flow solution was coupled to a two-equation integral 2D boundary layer model. The result is a sophisticated tool for solving the problem of both steady and unsteady viscous flow around streamlined lifting bodies such as wings or blades of turbomachines in external flow. The key aspect of the model is a quasi-simultaneous computation using interaction coefficients that allow solution of boundary layer with transition and other regions of strong interaction. The advantages and shortcomings of the new model are discussed based on the comparison with CFD results and the results of an advanced lifting line model. An elliptic wing with NACA4415 airfoil was chosen as a test case for comparison. Drag evaluation in the Trefftz plane was used as an alternative method for drag calculation in order to minimize force over surface integration error.
