The flow structure about a segmented projectile in hypersonic turbulent flow has been studied. The Reynoldsaveraged Navier-Stokes equations were solved numerically by application of the implicit monotonized scheme of second-order accuracy, the modified Newton's method, and the Christoffel-Schwarz grid-transformation technique. A strong interference effect has been found. The effect can be chara...

We have calculated the Is-Is charge transfer probability for large projectile scattering angles in asymmetric ion-atom collisions, using the strong-potential Born approximation and including the effect of recoil on the projectile states non-perturbatively. A significant angular dependence is found. Numerical results for Is-Is capture in 0.320 MeV proton impact on C and Ne are presented, showing...

Optical limit Glauber theory calculations of reaction cross sections, used to deduce nuclear sizes from high energy data, are studied in the case of a deformed projectile ~or target!. We show that a previously applied formula, used to adjust the root-mean-squared radius deduced assuming spherical projectiles, is consistent with results which treat the projectile deformation explicitly within th...

Shotguns are usually used to fire multiple pellets; however, they are capable of firing a single projectile in the form of a slug. Although rare, shotgun slug injuries are severe, producing wounds comparable to those inflicted by high-velocity weapons with the potential for even more tissue destruction because of the slug's size and mass. We report the first survivor of a close range shotgun sl...

Two existing global medium-energy nucleon-nucleus phenomenological optical model potentials are described and compared with experiment and with each other. The first of these employs a Dirac approach (second-order reduction) that is global in projectile energy and projectile isospin and applies to the target nucleus 208 Pb. Here the standard S-V (isoscalar-scalar, isoscalar-vector) model has be...

During high-speed water-exit of the supercavitating projectile, cavity interacts with free surface and collapses, instantaneous high collapse pressure impacting on projectile. In order to study characteristics during numerical based Reynolds-averaged equation volume fluid multiphase flow model is conducted in this paper. The results show that near will gradually become larger movement projectil...
