Slug Flow Model Lesson-2

This lesson covers the concept of Slug Flow Model in the context of two-face flow and heat transfer. It delves into the understanding of non-dimensional numbers to specify the velocity of the slug bubble, predicting the velocity using drift flux model and laminar regime, and calculating the film superficial velocity around the gaseous plug inside a vertical tube. The lesson also explains the assessment of pressure drop inside the horizontal slug flow. It uses a schematic to illustrate the repetitive pattern of gaseous Slug and gaseous plug and liquid slug. The lesson further discusses the calculation of terminal velocity of a bubble, liquid film superficial velocity, bubble velocity in horizontal slug flow, and pressure drop inside a horizontal slug flow.
