A mixture model with modified mass transfer expression for cavitating turbulent flow simulation

Abstract

Purpose

The purpose of this paper is to provide a mixture model with modified mass transfer expression for calculating cavitating (two‐phase) flow.

Design/methodology/approach

The mass transfer relations are derived based on the mechanics of evaporation and condensation, in which the mass and momentum transfer count for factors such as non‐dissolved gas, turbulence, surface tension, phase‐change rate, etc.

Findings

As shown by two calculation examples, the modified model can predict the cavitating flow with high accuracy, agreeing well with experimental results.

Originality/value

The methods described are of value in improving stability in numerical calculations.
