Euler and Navier-Stokes Equations paths. The vanishing of the commutator means that vortex lines are carried by the ﬂow. The ﬂow is the path map a→ X(a,t). The connec-tion between the Lagrangian description and the Eulerian one is given by the relations u(x,t) = ∂X(a,t) ∂t, x= X(a,t).Cited by: In order to investigate the calculation ability of meshless method and calculation precision for lift and drag force coefficient based on N-S equations with S-A turbulence model and Euler equations, numerical simulation of flow field around the DLR-F4 wing-body, supplied by the AIAA Drag Prediction Workshop, is employed using meshless : Xin Jian Ma, Jun Jie Tan, Deng Feng Ren, Fang Wang.

Cited by: In the field of fluid mechanics, an explicit meshless solution method is proposed for the solution to Euler/Navier-Stokes Equations (Batina, ). And later, implicit methods are proposed to improve the early explicit method (Morinishi, ; Hongquan, ). The lower–upper symmetric Gauss–Seidel (LU-SGS) algorithm, which is implemented in a matrix-free form like the one used in the finite-volume method, is introduced in the work to speed up the convergence.

The proposed approach is validated by its application to simulate transonic flows over a NACA by: A new, high-order, conservative, and efficient method for conservation laws on unstructured grids is developed.
