The paper presents the results of numerical analysis oriented at the optimum design of the Venturi nozzle applied in the around-the-pump proportioning systems of fire suppression foam. The dimensions of the system are limited by the available space in the fire engine on one hand and the effective operation on the other hand. The computational fluid dynamics research tool was used within the confines of carried out analysis. Numerous designs were investigated in term of mass flow rate of the foam compound. The obtained results allowed to improve the efficiency of the system by 9.5 % in comparison to the baseline design.
