Balachandar, S. Zeng, Lanying 2015-09-28T16:23:47Z 2015-09-28T16:23:47Z 10000-01-01 2007 2007 Thirdly, we investigate the interaction of a finite-sized particle embedded in a turbulent channel flow. Particles of various sizes have been located at two specific wall-normal locations, the buffer region and the channel center. Near-wall region mechanisms are observed consisting of such different events as bursting, sweep, and ejection, whereas channel center can be considered as nearly isotropic turbulence. We compare the computed forces with the standard force formulations and analyze possible mechanisms for their deviations. Further, we analyze the back effects that the particle imposes on the turbulence field---in particular, the wake responses to the ambient turbulence and the turbulence modulation by the particle for the energy and wall shear stress.
