چکیده
A nite-volume method is presented for the computation of compressible ows of two immiscible uids at very di erent densities. The novel ingredient in the method is a twouid linearized Godunov scheme, allowing for ux computations in case of di erent uids (e.g., water and air) left and right of a cell face. A level-set technique is employed to distinguish between the two uids. The level-set equation is incorporated into the system of hyperbolic conservation laws. 2000 Mathematics Subject Classi cation: 65M60, 76N99, 76T10

Numerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
متن کاملQuasi-Static Numerical Simulation of Missile Staging
In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...

متن کاملWater hammer simulation by explicit central finite difference methods in staggered grids
Four explicit finite difference schemes, including Lax-Friedrichs, Nessyahu-Tadmor, Lax-Wendroff and Lax-Wendroff with a nonlinear filter are applied to solve water hammer equations. The schemes solve the equations in a reservoir-pipe-valve with an instantaneous and gradual closure of the valve boundary. The computational results are compared with those of the method of characteristics (MOC), a...
