Abstract

The drag crisis in flow past a sphere is modeled within the framework of the recently formulated scale-resolving hybrid RANS−LES approach, which includes a semi-empirical model of laminar-turbulent transition. The calculations performed in a wide Reynolds number range show that the complex model used yields a qualitatively adequate description of all aspects of the drag crisis including such fine effects, as the growth of the side force oscillation amplitude at near-critical Reynolds numbers. At the same time, the results obtained indicate that very fine computation grids should be used for obtaining qualitatively accurate predictions of the critical Reynolds number and the details of laminar-turbulent transition in near-critical flow regimes.

采用尺度解析法对球体上的阻力危机进行数值模拟
摘要 在最近制定的尺度解析混合 RANS-LES 方法框架内对流经球体的阻力危机进行了建模,该方法包括层流-湍流过渡的半经验模型。在很宽的雷诺数范围内进行的计算表明,所使用的复杂模型可以定性地充分描述阻力危机的所有方面,包括细微效应,如接近临界雷诺数时侧力振荡幅度的增长。同时,所获得的结果表明,应使用非常精细的计算网格来获得临界雷诺数的定性准确预测以及近临界流态下层流-湍流过渡的细节。
