One-dimensional two-phase flow

Title

Prerequisites

Fundamentals of fluid mechanics

Objectives

Prediction of two-phase flow phenomena with system codes

Content

The course teaches the fundamentals of physical modeling of a flow of liquid and steam in tubes and introduces to the prediction of pressure losses, density and mass flows distributions with one-dimensional system codes. It includes in particular:

• Flow patterns and their prediction with flow maps.
• The homogeneous flow model and its applications.
• The drift flux model for bubbly flow.
• The separate flow model with 6 balance equations for general predictions of two-phase flow.
• Critical mass flow with sonic velocity of two-phase flow through nozzles and valves.
• Dynamic effects of two-phase flow.

The course includes exercises with the system code APROS 6, a general one-dimensional system code for nuclear and conventional power plants.
