This study delves into the electrophysical processes and intricate fluid dynamics of an electrical-explosion-induced bubble in water. A fine copper wire is heated up exploded to dense metallic aerosol (vapor–drop mixture) via a μs-timescale 10 kA current pulse, crossing wide range density–temperature parametric space. High-speed photography along with discharge diagnostics reveals two modes for plasma development (restrike) inside explosion products: gas volume ionization. Experimental...
Abstract Underwater pulsed discharge, where intense reactions between ionized gas and condensed-state water exist, can be a joint problem of both physics chemistry. The study tries to build comprehensive visualization nanosecond-risetime discharge initiated by conductive coating its successive multi-physical effects. scenario is established via pair thin-plate electrodes positioned on sides the coating, diagnosed using high-speed backlight photography synchronized with electrical optical...
A kind of numerical simulation method for turbulent combustion in underwater vehicle combustor is presented. The described with κ−ɛ standard turbulence model, eddy dissipation model and discrete droplet liquid. Velocity field, temperature field concentration are obtained. effect inlet pressure difference spray the analyzed. It draws conclusion through simulation: as grows, characteristic enhances, efficiency increases. result provides a reference optimization combustor.
On the basis of Umansky box-girder torsion theory, software ANSYS is applied to simulate related engineering model. In considering a variety live load conditions, lateral stability multi-span single-pier variable cross-section under eccentric analyzed. Analysis results reveal that different working factors affecting transverse bridge and proportion value on each, such as gravity, span ratio distance between support are different; When overload 2 times larger, safety coefficient decreases...
It is anticipated that the 6th Generation (6G) mobile network security does not only solve problems posed by new technologies, services, and applications, but also presents endogenous feature which different from patching or plug-in appearing in traditional networks. Based on features of 6G network, this paper analyzes scenarios challenges, then puts forward requirements including enhanced trust, resilient autonomy, digital twin security, ubiquitous security. Finally key technologies their...
