Numerical (error) issues on compressible multicomponent flows using a high-order differencing scheme: Weighted compact nonlinear scheme
TL;DR: Results show that the different types of numerical oscillation in pressure field are generated when fully conservative form or interpolation of conservative variables is selected, while quasi-conservative form generally has poor mass conservation property, and primitive variable interpolation is considered to be better choice for compressible multicomponent flows in the framework of WCNS.
Proceedings ArticleDOI
Airfoil Flow Experiment on the Duty Cycle of DBD Plasma Actuator
TL;DR: In this paper, the influence of burst frequency f, input voltage sine wave frequency fbase and burst ratio BR on the stall control is discussed with the conditions Rec=44,000, 63,000.
Journal ArticleDOI
A simple interface sharpening technique with a hyperbolic tangent function applied to compressible two-fluid modeling
TL;DR: The results show that the interface is significantly sharpened with this technique, and its sharpness is well controlled by one parameter, and the robustness of the scheme does not change with sharpening the interface in the range the authors investigated.
Journal ArticleDOI
A new technique for freestream preservation of finite-difference WENO on curvilinear grid
TL;DR: In this article, a new technique for a finite-difference weighted essentially nonoscillatory scheme (WENO) on curvilinear grids to preserve freestream is introduced.
Journal ArticleDOI
