Abstract
Two-dimensional onset of vortex shedding study for flow through y-periodic objects provides the guiding information for the optimal design of compact systems. Three-dimensional DNS study of interactions between isotropic turbulence and finite sized spheres address the bi-directional influence in the regime of particle size much larger than the Kolmogorov scale.
