Here you can adjust the wet particles' lifespan.
Splash min lifetime
This When a splash particle is created, it has a radius of 1.0 and RealFlow calculates an expected lifetime based on the settings under “Splash min/max lifetime”. During its lifetime, the radius is constantly decreasing and when it reaches 0.0, the particle dies. When a splash particle hits the core fluid surface it will be deleted immediately regardless of its current lifetime. This is the minimum lifetime of the wet particles given in seconds [s]. Please remember that wet particles are considered splashes and hence they share the same parameter names. The lifetime parameters are a very good method of controlling the amount of wet/splash particles. If you use different values for “Splash min lifetime” and “Splash max lifetime”, the actual lifetime will be somewhere between both settings. When a splash particle hits the core fluid surface it will be deleted immediately regardless of its current lifetime.
