Numerical Investigation of the Drop Formation Mechanism and Study of the Droplet’s Pressure Contour

The current study provides the numerical investigation of the drop formation mechanism. Volume of fluid methods is used for the numerical simulation. The analysis contains 2% Polyacrylamide as the main fluid that dispersed in the air. For analyzing the drop mechanism, the Velocity Vector Contours are studied. Velocity contours also explain the phenomenon of the satellite drop formation process. Pressure Contours demonstrate the variation of pressure in the drop at various time steps. Pressure varies exponentially at the necking zone for each step of the drop formation. The variation of velocity at the leading edge of the drop is also investigated. The magnitude of the velocity decreases during the neck formation, because the liquid upside and downside the necking point tugs one another towards their side.
