Application of detached-eddy simulation to free surface flow over dunes

Abstract: Detached-eddy simulation (DES) is proposed for simulating shallow water flow in the present paper. Compared to the traditional numerical model used in river flow simulation that is based on hydrostatic assumption, the non-hydrostatic pressure terms are introduced into the momentum equations to improve the accuracy of simulating flow over a distinct, uneven bottom. The numerical scheme is a finite volume method based on an unstructured grid in the horizontal plane, and the σ coordinate in the vertical direction… Show more

“…Therefore, IDDES is selected for simulating the aerodynamic behavior of trains. The improved delayed detached eddy simulation method (IDDES) was selected to simulate the flow field in this study as this method combines the advantages of the Reynolds-Averaged Navier-Stokes framework and the Large Eddy Simulation, which have been discussed in detail (Dong et al, 2018;Gritskevich et al, 2012;Zhang et al, 2015). Finally, IDDES with SST κ-ω turbulence model was determined for simulations, and this method has been successfully applied to the simulation of train aerodynamic characteristics by numerous researchers (Chen et al, 2019;Dong et al, 2019;He et al, 2018;Li et al, 2018;Li et al, 2019;Niu et al, 2018b;Tan et al, 2019;Zhang et al, 2019;Zhou et al, 2020).…”

“…With the development of computational technology, computational fluid dynamics (CFD) methods, such as steady and unsteady simulations, RANS simulations based on different turbulence models, and direct numerical simulations, are frequently used to predict total aerodynamic coefficients, dynamic derivatives, and complex flow phenomena (Hu, Li, Han, Steve, & Xu, 2016;Seyfert & Krumbein, 2012;Zhang, Wang, Liang, & Liu, 2015). So far, the numerical investigations on the Magnus effect of spinning finned projectile are slight.…”
