Simulation Of Mixed Fluid Phase Transformation Based On SPH

In this paper,a SPH-based simulation method for phase transition of mixed fluids is introduced,which is used to simulate the solidification and melting of mixed fluids.By combining the simulation of the mixed fluid and the phase change simulation,a more accurate fluid simulation can be carried out.These changes make fluid animation more expressive.The method presented in this paper uses volume fraction to represent the mixing of different fluids.The phase transition process includes liquid solidification and solid melting.Mixed fluids are divided into miscible and immiscible fluids.The properties of the miscible fluids will change,such as melting point,resulting in different effects from those of the immiscible fluids.The method introduced in this paper can accurately calculate the property changes of miscible fluids.Generate more effective fluid animation.Prior to this,computer graphics has a lot of research on mixed fluids and phase transition simulation,most of which focus on the study of immiscible fluids,in recent years more and more research on miscible fluids,including particle-based,grid-based and mixing methods.Nevertheless,there is little research on the phase transition of mixed fluids.Unlike ordinary fluid phase transitions,mixed fluid phase transitions involve many improvements,such as the melting point of the mixture.This paper achieves these effects well.In addition,for particle-based fluid simulation,it is usually necessary to construct the liquid level.The liquid level of mixed fluids will be mixed together,so a method is needed to express the mixing between fluids.In this paper,a method of reconstructing the liquid level of mixed fluids is used to calculate the liquid level of mixed fluids.The calculated liquid level can better represent the fusion of different fluids.
