Investigating the Influence of Shock Waves on the Dielectric Characteristics of ZMTC Crystals
Abstract: Zinc mercury thiocyanate (ZMTC) is an organometallicnonlinearly optical (NLO) single crystal that has been grown in an aqueous solution using the SR technique. Novel, non-destructive method is suggested and shown to enhance the electrical properties of crystals through the use of shock waves. A tabletop shock tube, operating at a Mach number of 1.7, generates shock waves that are subsequently loaded into a zinc mercury thiocyanate (ZMTC) crystal. This process, …

Numerical Analysis of Oblique Impinge shock-wave/turbulent boundary-layer interaction Using Reynolds Average Navier Stroke Equations
Abstract: Interaction of shock waves with turbulent boundary layer plays an important role in the design and operability of high-speed aerospace vehicles and air-breathing engines. During interaction, the adverse pressure gradient of the shock is often strong enough to separate the boundary layer. Reynolds averaged Navier-Stokes simulations using conventional turbulence models do not predict the correct size and shape of the separation bubble in strong shock/turbulent boundary-layer interactions. The corresponding surface …
