Current achievements on bubble dynamics analysis using MPS method

Bubble dynamics always exist in nuclear reactor system which affect the fluid flow, heat transfer and moderation of neutrons. Therefore it is necessary to do some related researches that can be of significance to the nuclear engineering. With the aim to achieve better bubble dynamics simulations, a sequence of direct numerical simulation methods have been proposed in recent years. Specifically, as a fully Lagrangian method, the Moving Particle Semi-implicit (MPS) method has the capability to accurately track the interface. The bubble dynamics is one of the important benchmarks for testing the capability in the simulation of multiphase flow using MPS method. Due to the discontinuity of interface properties such as density, viscosity, it is a great challenge to simulate bubble dynamics with actual properties by MPS method. In view of this, this article carries on a comprehensive review and the summarization to the current researches in the basic models of the original MPS method and the modified MPS methods for bubble dynamics, and proposes the future perspectives in this field. Meantime, the characteristics of different modified MPS methods are also discussed in detail by the comparison of the corresponding simulation results. To sum up, this article could provide ideas for further improvements of MPS method and promote its applications in the field of nuclear engineering.
