Through modification of the equation of state applicable to the non-volatile salt solution and characterization of the effect of solute concentration on the physical properties of the solution, a lattice Boltzmann pseudopotential model was developed and used to study the pool boiling processes of pure water and NaCl solutions. The model quantitatively verified the equilibrium vapor pressure reduction and boiling point rise of the NaCl solution with solute concentration. The complete pool boiling curves of pure water and the NaCl solution were simulated, and the differences in bubble behaviors and heat flux evolutions in pure water and the NaCl solution at different superheats were analyzed. The results revealed that the difference of heat flux between water and NaCl solution in the nucleate boiling regime is dominated by the nucleation site density and bubble departure frequency at lower superheats, while dominated by the bubble interactions at larger superheats. As a result, the NaCl solution presents a lower nucleate boiling heat flux than that of water when the imposed superheat is smaller than a critical superheat, while it exhibits a larger heat flux even a higher critical heat flux than water when the superheat is higher than the critical superheat. Furthermore, the lower bubble departure frequency in NaCl solution film boiling was captured by simulation. The simulated film boiling heat flux of the NaCl solution was smaller than that of water, and both the simulated results fitted the Berenson correlation well.

通过对适用于非挥发性盐溶液的状态方程的修正和溶质浓度对溶液物理性质影响的表征，建立了格子玻尔兹曼赝势模型，用于研究纯水和水的池沸腾过程。氯化钠溶液。该模型定量验证了NaCl溶液随溶质浓度的平衡蒸气压降低和沸点升高。模拟了纯水和NaCl溶液的完整池沸腾曲线，分析了不同过热度下纯水和NaCl溶液的气泡行为和热通量演化的差异。结果表明，在成核沸腾状态下，水和 NaCl 溶液之间的热通量差异在较低过热度下受成核位点密度和气泡离开频率的影响，而在较大过热度下则受气泡相互作用的影响。因此，当施加的过热度小于临界过热度时，NaCl 溶液呈现出比水更低的核沸腾热通量，而当过热度高于临界过热度时，它表现出更大的热通量，甚至比水更高的临界热通量。临界过热度。此外，通过模拟捕获了 NaCl 溶液薄膜沸腾中较低的气泡离开频率。NaCl溶液的模拟薄膜沸腾热通量小于水，模拟结果均符合Berenson相关式。
