Nozzle prototype for a diesel fuel reformer was investigated using numerical simulation. The main goal was to increase the rate and degree of fuel evaporation, as well as to improve the mixing characteristics between diesel fuel and superheated steam. A nozzle design was proposed with two internal regions, in which jets with opposite swirl directions were created. The simulation of mixing and evaporation of liquid fuel droplets and steam jets was performed in a finite volume formulation. The results of simulations show good uniformity of the mixture concentration downstream the nozzle exit, as well as high degree of evaporation, which is important for catalytic processes.
