For lattice Boltzmann methods based on entropy functions, we derive a collision integral which enables simple identification of transport coefficients, and which circumvents construction of the equilibrium. Implementation of the two-dimensional hydrodynamics demonstrates considerable increase of stability with respect to conventional lattice Boltzmann schemes.
对于基于熵函数的格子玻尔兹曼方法，我们推导了一个碰撞积分，它能简单地确定输运系数，并且避免了平衡态的构建。二维流体动力学的实现表明，相对于传统的格子玻尔兹曼格式，其稳定性有显著提高。
