Numerical Simulation Analysis of Heat Storage and Release Performance in Baffle plate Phase Change Energy Storage Tank

摘要

Phase change energy storage technology is a kind of latent heat storage, phase change material of absorbing or releasing large amounts of latent heat in phase change, with larger heat flow density and in the process of phase transformation temperature remained unchanged, is the ideal way for storage. A phase change material is arranged in the water tank, and the heat storage capacity of the water tank can be greatly improved, As the heat transfer area increases, the baffle plate phase change water tank has better heat transfer effect, However, the heat storage and release capacity of the phase change energy storage water tank is affected by many factors. In this paper, we build a physical model and use CFD simulation software as the platform, Numerical simulation is used to simulate the heat storage and release characteristics of the phase change water tank at different inlet temperatures and inlet speeds. It provides a reference for the design of the actual phase change energy storage water tank, and it is beneficial to improve the heat storage and discharge performance of the phase change energy storage water tank.
