1. Aerosol coagulation

Aerosol coagulation is the process of adhesion or fusion of one aerosol particle with another.

When this approach, leading to contact, takes place solely by means of Brownian motion (diffusion), we call it thermal coagulation or Brownian diffusion. In fact, as we shall see, this phenomenon only occurs if the concentration of aerosols in the medium under consideration is sufficient.

In turbulent conditions, velocity fluctuations within the fluid can influence particle movement, leading to two mechanisms. The first is turbulent diffusion coagulation: small particles follow random fluctuations in fluid velocity, and two aerosols in two neighboring vortices may collide. The second mechanism is inertial turbulent coagulation: since the density of the particles is different from that of the fluid, two...
