چکیده
Abstract In the numerical simulation research for underwater explosion, selection of parameters has a great influence on results calculation. Based one-dimensional spherical symmetry model, this paper systematically studies three factors: grid size, water state equation and artificial viscosity coefficient important physical explosion when TNT explosive is exploded in water. The selected are shock wave intensity, maximu m radius bubble pulsation period bubble. A series carried out explosions with different sizes, so as to obtain corresponding recommended grids that meet calculation accuracy. equations discussed. effect analyzed. Finally, similarity law model studied verify universality parameters.

A Second Order Accurate Method in Simulation of Underwater Explosion
In this paper, a numerical scheme is proposed for the multi-fluid compressible flows. This method is applied to the problem of underwater explosion. The proposed scheme is basically the extension of Godunov method in gas dynamic problems to the multifluid environments and is second-order accurate in space. In this method, also, the problem of artificial mixing of two different phases on Euleria...

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
sph simulation of waves associated with underwater explosion
the current manuscript presents the validation of smoothed particle hydrodynamics (sph) techniques for wave generation by underwater explosion, utilizing the so-called dualsphysics numerical model. this numerical method is used to analyze generated waves which are initiated by man-made or natural explosions below free surface level of sea. in spite of the modeling limitations (e.g. absence of o...
