Abstract: | Direct numerical simulation (DNS) has been carried out to study the combined effects of rotation and induced swirl on the fully developed turbulent pipe flow at Reynolds number Reb = 4900, based on the bulk velocity and the pipe diameter. The swirl is induced by a body force in the tangential momentum equation, which produces a tangential velocity field in the near wall region. Results from a single swirl along with five different strengths of rotation are considered. The serial finite difference DNS code used by Sahoo et al. [1] has been made parallel by using MPI library. The grid used consists of 128 × 96 × 512 grid points in −, r− and z− directions, instead of 65×97×65, used by Sahoo et al. [1]. The effects of rotation and swirl on turbulent structures are investigated in detail. |
