A novel parallel implementation of hybrid DNS (Direct Numerical Simulation) code for simulating collision-coalescence of aerodynamically interacting particles in a turbulent flow has been developed. An important application of this code is to quantify turbulent collision-coalescence rate of cloud droplets, relevant to warm rain formation, under physically(More)
Collision-coalescence of cloud droplets in a turbulent air flow is an essential step for warm rain precipitation, therefore, the parameterization of turbulent collision-coalescence rate of cloud droplets is central to the modeling of cloud dynamics in particular and to weather prediction in general. In the last few years, we have developed a hybrid direct(More)
