The Effect of Temperature Variations on Wood’s Metal Plate Melting Simulation by Using MPS

Abstract

Two-dimensional simulation of Wood’s Metal Plate (WMP) Melting Process has been conducted by varying the molten temperature. This simulation was performed by using Moving Particle Semi-Implicit (MPS) method which can calculate the Navier-Stokes and heat transfer equation without divining mesh system. As a substitute, particles are selected to represent every part of simulation such as fluid, wall and dummy type. The experiment of WMP melting process has been conducted by Sudha (2018). The molten Wood’s Metal was originally set at 573 K. In this simulation, the holes formation in WMP will be investigated as a consequence of molten temperature variation. Furthermore, temperature distribution at top side of WMP and solid-liquid phase change will be analyzed for initial temperature of molten are 523 K, 473 K and 423 K. The results show that the phases change significantly in a short time when the molten temperature is increased. However, until the end of simulation which on 1.5 s just for molten temperature 573 K shows the breaching process to the WMP. This study can be implemented when the reactor nuclear severe accident happened.

Numerical Study on Relocation Process of Al, Fe, and Pb by Using the Moving Particle Semi-Implicit Method During Severe Accident of Reactor

“…From the obtained results, the relocation pattern of the liquids is similar to the results obtained by Ilham et al (2018) using a different liquid, where the MPS result is compared to the experiment. Therefore, it is expected that the temperature did not significantly impact the relocation process, which agrees with Hidayati et al (2020). Furthermore, the splash pattern of this study is similar to the results of Hidayati et al (2021).…”
