Abstract A novel method to create a discontinuous gaseous interface with minimum-surface feature by the soap film technique is developed for three-dimensional (3D) Richtmyer–Meshkov instability (RMI) studies. The formed free of supporting mesh and initial condition can be well controlled. Five air/SF 6 interfaces different amplitude are realized in shock-tube experiments. Time-resolved schlieren planar Mie-scattering photography employed capture motion shocked interface. It found that at...
The interaction between a cylindrical inhomogeneity and weak planar shock wave is investigated experimentally numerically, special attention given to the patterns vortex dynamics in this scenario. A soap-film technique realized generate well-controlled discontinuous cylinder (SF6 surrounded by air) with no supports or wires shock-tube experiment. symmetric evolving interfaces few disturbance waves are observed high-speed schlieren photography. Numerical simulations also carried out for...
A control method is developed to suppress pressure oscillations induced by supersonic cavity flow using high-speed upstream injection. The injection generated with a large blowing coefficient through channel, which guides the airflow off in leading edge of cavity. Wind tunnel experiments are performed validate Mach 1.8 and 2.0 flows over length-to-depth 6 Six dynamic transducers used characterize oscillation. remarkable suppression fluctuation realized controlled flow. overall sound level...
Abstract ZnO is modified by Cu 2 O the process of precipitation and calcination. X-ray diffraction has shown that O/ZnO catalysts are made highly purified cubic hexagonal ZnO. Scanning electron microscopy transmission have adhered to surface O. Due doping O, absorption range catalyst shifted from ultraviolet visible region due diffuse reflection. photoelectron spectroscopy photoluminescence spectra confirmed there a substantial interaction between two phases resultant catalyst. The...
A electrocoagulation (EC)/peanut shell (PS) adsorption coupling technique was studied for the removal of malachite green (MG) in our present work. The addition an appropriate PS dosage (5 g/L) resulted remarkable increase efficiency MG at lower current density and shorter operating time compared with conventional EC process. effect density, pH solution, initial concentration were also investigated. maximum 98% under optimum conditions 5 min. And it 23% higher than that Furthermore, unit...
The Richmyer-Meshkov instability of a three-dimensional (3D) SF_{6}-air single-mode interface with minimum-surface feature is investigated experimentally. produced by the soap film technique subjected to planar shock and evolution shocked captured time-resolved schlieren photography. Different from light-heavy case, phase inversion occurs in shock-interface interaction bubblelike structure observed behind interface, which may be ascribed difference pressure perturbation at different planes....

Aluminum/Polytetrafluoroethylene (Al/PTFE) is a representative energetic material, which can be used in many fields including defense weapon fragments, insensitive penetrator or oil-well perforation. However, the insufficient mechanical strength of traditional ingredient has seriously restricted its penetration ability, and additives improve compressive at expense reactivity. Hence, innovative component design advanced manufacturing technology should applied to Al/PTFE composite. In this...
