Particle-turbulence interaction in homogeneous isotropic turbulence

A morphing continuum approach for simulating particle-laden turbulent flow is presented. A morphing continuum theory (MCT) describes a continuum composed of smallscale structures that affect the global motion of the fluid. The current study employs the MCT small-scale structures as immiscible particles, and investigates their impact on modulating the characteristics of turbulence. The study presents a non-dimensionalized form of the MCT incompressible governing equations, with new dimensionless groups that convey the impact of the particles on the flow. The MCT governing equations are employed to investigate the dynamics behind turbulent particle-laden in a numerical simulation of homogeneous isotropic turbulence (HIT).
