Simulation of an Internal Nozzle Flow Using an Euler-Lagrange Method


In this work, an Euler-Lagrange method to simulate cavitation and predict cavitation erosion is presented. The method considers bubble motions as well as growth and collapse of a discrete number of single, spherical bubbles. A two-way coupling approach is implemented so that both liquid phase and vapour bubbles interact with each other. In contrast to Euler-Euler methods, this allows a more detailed simulation of bubble transport and dynamics. We used the developed method to simulate the internal cavitating flow in a nozzle.
