“…8,30 The in-house CFD solver GFSI is used to solve the Euler equations, which has been fully tested for fluid-structure simulations in our previous works. 42,43,46,47 The integral form of the Euler equations can be written as:where W=[ρ,ρu,ρv,ρw,e]T is the vector of conservative variables, p is the density, u, v, and w are the velocity components in x, y, and z directions, and e is the internal energy per unit mass. F(W,Vgrid) is the inviscid flux vector.…”
