通过插入位置和时间相关的“源”或“强迫”条款到微观演化方程的格子玻尔兹曼流体和治疗的广义计划内通常的查普曼-Enskog方法，我们表明，新兴的动态晶格流体可能会被有效地改造。我们的调整方法是通过实施圆柱极坐标形式的连续性和动量方程的矩形格子和管流产生的结果。通过直接系统地调整模拟，我们的方法产生的结果与理论非常一致。
By inserting position and time dependent "source" or "forcing" terms into the microscopic evolution equation of a lattice Boltzmann fluid and treating the generalized scheme within the usual Chapman-Enskog methodology, we show that the emergent dynamics of the lattice fluid may be usefully transformed. Our method of adjustment is demonstrated by implementing the cylindrical polar coordinate form of the continuity and momentum equations on a rectangular lattice and generating results for pipe flow. With straightforward systematic adjustment of the simulation, our approach produces results in excellent agreement with theory.
