Implicit wall modeling method for large eddy simulation based on high-resolution spectral cell method and its application

This invention discloses an implicit large eddy wall simulation method based on the high-precision spectral element method. This method constructs an implicit large eddy simulation (SVV-iLES) based on the hp-type spectral element method combined with the spectral viscosity elimination method (SVV), and implements wall simulation within this framework. The method includes the following steps: adjusting the boundary layer according to the actual situation of the turbulent boundary layer to ensure that the corresponding points fall within the logarithmic region; interpolating the element velocity and velocity u within the spectral element method code framework to obtain velocity components parallel to the wall velocity, which are then substituted into the algebraic model; analytically obtaining the wall stress through the algebraic model; and finally, modifying the boundary conditions in real time using the logarithmic rate model to complete the simulation. This significantly reduces the enormous computational burden caused by fine boundary layer meshes in flow problems. This invention also proposes an application of this simulation method to high Reynolds number wall flow scenarios, providing an efficient foundation for accurate flow calculations.
