Viscous liquid explosion dispersion Model

To build the model for viscous liquid explosion dispersion is of great significance to numerically simulating viscous liquid explosion dispersal process. The explosion dispersion of viscous liquid is a complex physical process including initial driving of fluid, cavitation effect, formation of fluid ring, formation and fracture of jets, droplet breakup. According to flow characteristics in different stages and different phenomena, the mathematics model of Newtonian viscous fluid's explosion dispersion was established. The liquid dispersal velocity, the fluid dispersal radius and the distribution of droplets size were obtained through calculation. The results showed that the fluid dispersal radius is proportional to the fluid viscosity, while the curvature of the fluid dispersal velocity attenuation curve is inversely proportional to the fluid viscosity. The test was designed to verify the correctness of the mathematical model. It was shown that the test results agree well with those of calculation, the correctness of the model is verified.
