Title: | Numerical study of a linear shear flow past a rotating cylinder | Authors: | Chew, Y.T. Luo, S.C. Cheng, M. |
Issue Date: | Feb-1997 | Citation: | Chew, Y.T.,Luo, S.C.,Cheng, M. (1997-02). Numerical study of a linear shear flow past a rotating cylinder. Journal of Wind Engineering and Industrial Aerodynamics 66 (2) : 107-125. ScholarBank@NUS Repository. | Abstract: | The effects of shear rate on flow past a rotating circular cylinder in a linear shear flow have been investigated by using a hybrid vortex method at a Reynolds number of 1000. The velocity gradient of the shear flow K ranges from -0.3 to 0.3 and the rotational to translational speed ratio α is 0.5. The results show that the form of vortex shedding is controlled by the shear parameter K. The drag coefficient decreases with increasing |K|. On the other hand, the lift coefficient and Strouhal number increase as K increases. As K increases, the separation positions shift downstream, the wake becomes narrower and the amplitude of fluctuation of the instantaneous lift and drag coefficients decreases. | Source Title: | Journal of Wind Engineering and Industrial Aerodynamics | URI: | http://scholarbank.nus.edu.sg/handle/10635/58546 | ISSN: | 01676105 |
