Studying gas temperature variation upon aerosol injection

Аннотация

Variation of the temperature of gaseous combustion products upon pulsed injection of aqueous aerosols (water, NaCl solution, clay suspension) with droplet sizes within 40–400 μm has been experimentally studied at initial gas temperatures from 520 to 910 K. The motion of aerosol droplets in the counterflow of combustion products was visualized by panoramic optical techniques. It is established that the process of gas cooling depends on the degree of aerosol dispersion, NaCl concentration in solution, clay content in suspension, and the conditions of liquid phase injection.
