Solid particle may be a possible device for controlling the turbulence transfer of momentum and heat. We applied the direct numerical simulation (DNS) to investigate the particle-laden turbulence in fully-developed upward flow in a vertical channel. In this report, particular attention is focused on the influence of particle rotation. Rotating particles are distributed more uniformly in the channel in comparison with irrotational ones. Flow separation from irrotational spheres develops to hairpin vortices in near-wall region, while flow around rotational ones increases small scale turbulence in the mainstream region.
