Embodiment Construction
[0072] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.
[0073] Such as figure 1 Shown, the inventive method specifically comprises the following steps:
[0074] 1) Establish the heat transfer model of the object from solid to liquid. Using the method of particle modeling, the heat transfer model is designed, and three heat modes are divided to simulate the process of the object absorbing heat, the temperature rises, and the object changes from solid to liquid when it reaches the melting point.
[0075] 2) Calculate the droplet surface tension model using the smooth particle hydrodynamic model and interface mechanics theory.
[0076] The use of smooth particle dynamics to solve surface tension solves the problem of tension asymmetry caused by uneven particles and the phenomenon of particle aggregation and accumulation. After ice particles are transformed into water particles, they flow from the solid s...
