The phrase "a phase change model" is correct and usable in written English.
You can use it in contexts related to science, particularly in physics or materials science, to describe a model that explains the transition between different states of matter.
Example: "The researchers developed a phase change model to better understand how materials behave when subjected to varying temperatures."
Alternatives: "a state transition model" or "a phase transition framework".
We develop a Jacobian-Free Newton Krylov (JFNK) method for the solution of a two-dimensional convection phase change model using the incompressible Navier Stokes equation set and enthalpy as the energy conservation variable.
The phase change is simulated using the Lee phase change model assuming that mass is transferred in a constant pressure and a quasi-thermo-equilibrium state.
The phase change model was based on spherical ice crystal growth and an original enthalpy formulation.
The phase change model is validated against analytical similarity solutions in both two and three dimensions.
Droplet phase change model, which employs homogeneous nucleation theory, is used for predicting the appearance of droplets.
The employed phase change model considers temperature/enthalpy hysteresis and varying enthalpy temperature characteristics to more accurately simulate the phase change behaviour of the PCM boards compared to the standard default modelling approach in the commercial CFD codes.
In order to investigate the condensation heat transfer and pressure drop characteristics in tube-side flow of spiral wound heat exchanger (SWHE), a computational model based on two-fluid multiphase model, k-ε turbulence model and thermal phase change model was established considering the gravity and surface tension.
The liquid-gas interface tracking method and the liquid-vapor phase change model are key parts of accurate simulations of droplet impingement cooling.
In this study, to simulate melting and vaporization of the first wall in a water-cooled breeding blanket under VDE, one-dimensional heat equations were solved numerically by using an in-house first wall module, including phase change models, effective heat capacity method, and evaporation model.
