Commonly used rates for turbulence-induced coagulation are extended to non-spherical fractal like particles. The coagulation kernel homogeneity is used to predict gelation and self-preservation for various mechanisms of turbulence-induced coagulation and verified by detailed sectional simulations. For spherical particles, self-preserving distributions are attained in the inertial regime (dp >> η) while coagulation by accelerative mechanisms like fluid fluctuation or gravity in the viscous regime (dp
