Our team is trying to simulate and analyse the breakup length and SMD in a bipropellant coaxial swirl injector by varying the geometrical parameters. We are finding it difficult to nail the right Fluent setting especially in the species transport setting and DPM. We will be really grateful if someone could share their insight.

Propellants: liq oxygen and liq kerosene

Right now we are using RNG k-epsilon model
