提出了一种基于热格子Boltzmann模型的热格子Boltzmann模型，用于模拟一类强耦合的热流体动力学问题。该模型的新奇在于制定的焓密度分布函数来模拟温度场，在现有的内部能量密度分布函数的地方。所提出的模型具有明显的优势，在某种意义上说，它可以模拟某些类别的热流体传输问题，而不会面临数学困难，在处理额外的能源条款的早期内部能量密度分布函数的热晶格玻尔兹曼模型。
An enthalpy-based thermal lattice Boltzmann model is introduced for simulating a class of strongly coupled thermo-hydrodynamic problems. The novelty of the model lies in the formulation of an enthalpy density distribution function to simulate the temperature field, in place of the existing internal energy density distribution function. The proposed model has a clear advantage over the earlier internal energy density distribution function based thermal lattice Boltzmann model, in a sense that it can simulate certain classes of thermofluidic transport problems without facing mathematical difficulties in handling with additional energy source terms.
