用法:同OpenFOAM中vorticity,Q等后处理工具,执行Rotex -case XXX 涡是流体力学中的重要现象,但迄今为止,人们对涡的认识还很模糊,还未能给出一个有物理意义和被广泛接受的定义方法。多年来人们尝试了多种方法,早期曾采用涡量方法,但后来发现涡量和涡结构的关联性不高。后来,又发展了多种以速度梯度张量特征值为代表...

The program of Liutex is based on Professor Liu's theory, compiled with C++ language, which was embedded in OpenFOAM for post-processing. Several comparative studies on simple examples and realistic flows are studied to confirm the superiority of Liutex....

The numerical study is carried out in OpenFOAM by directly adding a source term to the Navier-Stokes equations, which is called the centripetal force model in Liutex method. A 2-D test case is examined to justify the proposed method in cavitating flow around Clark-Y hydrofoil, the simulation...
