a high pressure drop happens when heavy oil with high viscosity moves through the oil pipeline. a variety of methods to avoid this pressure drop is available. one of which is injection of chemicals to reduce the viscosity and ultimately reduce pressure drop. using the pipesim software, the effect of dispersion of nano and micro-particles into the oil has been simulated to study the amount of th...
After impact onto a smooth dry surface, a drop of viscous liquid initially spreads in the form of a thick lamella. If the drop splashes, it first emits a thin fluid sheet that can ultimately break up into droplets causing the splash. Ambient gas is crucial for creating this thin sheet. The time for sheet ejection, t{ejt}, depends on impact velocity, liquid viscosity, gas pressure, and molecular...
Lubricated surfaces have recently been introduced and studied due to their potential benefit in various configurations and applications. Combining the techniques of total internal reflection microscopy and reflection interference microscopy, we examine the dynamics of an underlying air film upon drop impact on a lubricated substrate where the thin liquid film is immiscible to the drop. In contr...
