Understanding and predicting the collision rate of small inertial particles in turbulent flows is of importance in many meteorological and industrial processes. For instance, predicting the time of rain initiation of warm clouds, which are known to be turbulent in their core, is still an open problem. Droplets in such clouds, which can be treated as inertial particles, are believed to grow to rain drop by coalescence due to collisions.
