Development of the new approach to the Brownian coagulation theory: Transition regime

The new approach for calculation of the collision frequency function in the two limiting regimes (continuous and free molecular) proposed in the previous paper [1] is extended to the general case including the intermediate transition regime. The collision frequency function in the transition regime is numerically calculated without using semi-empirical assumptions (from the literature). The best fit to the numerically calculated points can be attained with the new interpolation formulas that have a simpler form and higher accuracy in comparison with the semi-empirical models.
