Direct Numerical Simulation of Fully Resolved Vaporizing Droplets in a Turbulent Flow

Usage Details

The objective of this project is to enhance the understanding of liquid droplet vaporization and mixing processes in a turbulent flow. The numerical study employs direct numerical simulations (DNS) to examine the two-way interactions between freely moving vaporizing droplets and isotropic turbulence. The droplets will be fully resolved in 3D space and time, i.e. not treated as point particles, and all the scales of the turbulent motion are resolved down to the smallest relevant length and time scales (the Kolmogorov scales). The emphasis will be on the two-way exchange of mass, momentum and energy between the vaporizing droplets and the surrounding turbulent gas. The turbulence will be assumed isotropic as a first step before considering turbulent shear flows in future studies.
