为了实时模拟室内环境，在图形处理单元（GPU）上实现了一种基于晶格玻尔兹曼方法（LBM）的三维计算流体力学（CFD）技术。我们在一个试验室内和一个四床医院房间的简单模型中研究了湍流气流和温度的时间演变。将LBM的预测结果与传统CFD大涡模拟（LES）进行了比较。LBM计算结果与LES计算结果基本一致，计算时间明显加快。
A novel lattice Boltzmann method (LBM) based 3D computational fluid dynamics (CFD) technique has been implemented on the graphics processing unit (GPU) for the purpose of simulating the indoor environment in real-time. We study the time evolution of the turbulent airflow and temperature inside a test chamber and in a simple model of a four-bed hospital room. The predicted results from LBM are compared with traditional CFD based large eddy simulations (LES). Reasonable agreement between LBM results and LES method is observed with significantly faster computational times.
