Abstract: The equation of motion of a small spherical particle, entering the earth's atmosphere with cosmic velocities, has been integrated numerically. The results show that particles in the size range 0.1-100 ? attain terminal ...

Abstract: Numerical computations of collision efficiencies and certain coalescence parameters are presented for droplet pairs with Reynolds numbers up to 104. This corresponds to radii (for 900 mb, 0C) of up to 300 ?. The superposition ...
