THIS PROJECT IS TO COMPUTE THE FLOW OF FLUID AND THE MOTION OF A SOLID SPHERE IN A PRESSURE DRIVEN FLOW IN A ROUND PIPE BY THE METHOD DIRECT SIMULATION. OUR INTEREST IS IN THE LIFT FORCE ON THE SPHERE. TWO DIFFERENT CODES WILL BE USED TO COMPUTE THE SAME MOTION FOR VALIDATION. THE RESULTS WILL BE POST PROCESSED FOR CORRELATIONS GIVING THE DIMENSIONLESS LIFT FORCE IN TERMS OF POWERS OF THE GOVERNING PARAMETERS. THE GOAL IS TO GET DATA BASED FORMULAS FOR LIFT FROM NUMERICAL DATA. THE FORMULAS WILL BE COMPARED WITH DATA FROM REAL EXPERIMENTS.

本课题是用直接模拟的方法来模拟圆管内压力驱动流中流体的流动和固体球的运动。 我们感兴趣的是球体上的升力。 将使用两个不同的代码来验证验证动议。 结果将被用于相关性的后处理，从而给出以控制参数的幂表示的无量纲升力。 目标是从数值数据中获得基于数据的升力公式。这些公式将与真实的实验的数据进行比较。
