采用四阶有限差分格式和三阶Adams-Bashforth时间积分的直接数值模拟方法，研究了均匀横流作用下湍流强迫浮力羽流的行为。在通过平均1,200个瞬时三维场获得的统计定常状态下，对流动特征进行了唯象评估。在未来大涡模拟假设的讨论中，给出了关于湍流产生和耗散结构的初步结果。
The behaviour of a turbulent forced buoyant plume subjected to uniform crossflow is investigated utilising Direct Numerical Simulation (DNS) employing a fourth-order finite difference scheme and third-order Adams-Bashforth temporal integration. The flow features are assessed phenomenologically in the statistically steady state obtained by averaging 1,200 instantaneous 3D fields. Preliminary results on the structure of turbulent production and dissipation are shown in view of future discussions on LES modeling assumptions.
