Studies of the dynamic shape factor of aerosol agglomerates

Accepted: 1 February 1996
The dynamic shape factor was measured from the aerodynamic diameter and volume-equivalent diameter, for various aerosol agglomerates. The shape factor was related to the dynamic behaviour of agglomerates and the formation conditions of primary particles. A power law relationship between the dynamic shape factor and volume-equivalent diameter was found, in agreement with earlier studies. The exponent in the relationship gives the value of the fractal dimension, which enables comparison with the morphology of agglomerates and an indication of the formation mechanism.
