Boltzmann Model

A new lattice Boltzmann model, which is based on Shan-Chen (SC) model, is proposed to describe liquid-vapor phase transitions. The new model is validated through simulation of the one-component phase transition process. Compared with the simulation results of van der Waals fluid and the Maxwell equal-area construction, the results of new model are closer to the analytical solutions than those of SC model and Zhang model. Since the range of temperature and the maximum density ratio are increased, and the value of maximum spurious current is between those of SC and Zhang models, it is believed that this new model has better stability than SC and Zhang models. Therefore, the application scope of this new model is expanded. According to the principle of corresponding states in Engineering Thermodynamics, the simulations of water and ammonia phase transition process are implemented by using this new model with different equations of state. Compared to the experimental data of water and ammonia, the results show that the Peng-Robinson equation of state is more suitable to describe the water, ammonia and other substances phase transition process. Therefore, these simulation results have great significance for the real engineering applications.

Phase Transition Process

At the pore scale level, 2-D porous medium structures of porous media with different porosities (isotropic) and the same porosities (anisotropic) were constructed using quartet structure generation set. A random porous cavity was selected and combined with the lattice Boltzmann model to describe the gas-liquid phase transition process. Bubble generation, growth, mutual fusion, and collision as well as rebound process in porous media framework were investigated by simulating the phase transition phenomenon in porous media. Calculation results show that in three different heat loads, the maximum relative errors between the qualities of gas phase and liquid phase and theoretical solution of gas phase were 0.09%, 0.19%, and 0.32%, respectively, whereas the values for liquid phase were 0.11%, 0.38%, and 1.49%, respectively. Simulation results coincide with the theoretical solution perfectly, verifying the accuracy and feasibility of the model for random porous structures.
