A model for the impact interaction of bodies in a gas-dust protoplanetary disk

A model for the impact interaction of bodies in a gas-dust proplanetary disk was proposed. The input parameters of the model are differentiated or undifferentiated characteristics of the bodies being simulated. The bodies being simulated are represented as one or several totalities of N particles. The particles belonging to the totalities with different physical properties can be localized, which simulates a multilayer object. They can also be distributed chaotically in the entire volume. The mathematical realization of the model is based on the permeable particle method, which has made it possible to allow for the internal structure of objects and the complex character of the interaction. The proposed phenomenological description of dynamic collision processes occurring in the body's contact region adequately corresponds to the energy redistribution among processes of different nature.
