Pressure Loss in Two-Phase Flow

This lecture covers the pressure losses associated with different outlet conditions in two-phase flow, including liquid, mixture, and vapor outlets. The instructor explains the mass and momentum balances in the Homogeneous Equilibrated Model, focusing on constant area, flux-velocity, and perimeter. The lecture also discusses the energy balance, internal energy, and heat flux in the model. Various factors affecting pressure loss, such as monophasic and diphasic chunks, are analyzed. The presentation delves into the appearance of vapor in different sections, the evolution of vapor quality, and the friction coefficient. Practical examples and calculations are provided to illustrate the concepts.
