... equations is employed in order to accommodate the fluid domain motion. The free-surface/rigid body problem is formulated and solved in a fully coupled fashion. The numerical results illustrate the accuracy and robustness of the proposed approach. flow fluids hydrodynamics Navier-Stokes equations...

...Wei Yu; Xiaobing Zhang During a gun firing, the flow around a projectile will be developing and changing. In particular, the flow around the projectile is disturbed significantly when the projectile overtakes the muzzle flow. Furthermore, the projectile body pressure will also change substantially...

...Ragini Acharya; Kenneth Kuo This work presents a mathematical model for the two-phase flows in the mortar systems and demonstrates the application of approximate Riemann solver on such model. The mathematical model for the two-phase gas-dynamical processes in the mortar tube consists of a system...

...Kees Wapenaar and; Jacob Fokkema Diffusion, flow, and wave phenomena can each be captured by a unified differential equation in matrix-vector form. This equation forms the basis for the derivation of unified reciprocity theorems for diffusion, flow and wave phenomena. Contributed...

... antenna bending due to contact and bending due to flow. The analysis presented here shows that the key feature appears to be the taper of the antennae. The curvature of a tapered antenna due to an end-load is nearly constant whereas the curvature distribution due to flow is nearly a quadratic function...
