Acid rain in Austrian forests leads to a reduction of tree growth. In order to combat this situation several types of fertiliser has to be distributed over the forest areas. This is done by ejection from a truck based pressurised tank with additional pressurised air which in the form of a specific supersonic nozzle allows much higher exit velocity and thus enabling the system cover larger forest areas. Our contribution was the numerical calculation of the fluid dynamics of this mixture of air and a high amount of fertiliser particles.
