Viscous flow simulations are usually based on the Navier-Stokes equations representing the balance of mass, momentum, and energy. For many high Reynolds number flows, the viscous effects are only limited to small regions in the neighborhood of solid surfaces and in the wakes. We present here a zonal formulation with a reduced system of equations in the outer inviscid flow region. As in part I of this...
Simulation of inviscid flows are usually based on the Euler equations, namely, conservation laws of mass, momentum, and energy written in terms of conservative variables. We present an alternative formulation where the velocity components are calculated from a generalized form of the Cauchy-Riemann equations with a non-homogeneous term representing vorticity. The vorticity is obtained in terms of...
