Investigation of dust particles in Martian atmosphere mechanics of influence on entry vehicle thermal loads

In this work, results of multiphase supersonic flows study in Martian atmosphere entry conditions are presented. A mathematical model of gas-particle flow is developed and implemented in computational code based on the OpenFOAM framework. Simulations of particle behavior in gas flow around reentry v...

Zusammenfassung:In this work, results of multiphase supersonic flows study in Martian atmosphere entry conditions are presented. A mathematical model of gas-particle flow is developed and implemented in computational code based on the OpenFOAM framework. Simulations of particle behavior in gas flow around reentry vehicle are carried out. Mechanics of dust particle influence on heat flux are proposed and discussed.
