Summary:•Mars investigations, space vehicle in Mars atmosphere.•System of supersonic jets of vehicle brake motors.•Heat and mass transfer in flow field of jets. The paper simulates a structure and processes of heat and mass transfer in the system of exhaust jets of space vehicle brake motors during descent in the atmosphere of Mars. It is taken into account that the jet system is a chemically reacting gas medium formed by exhaust gases and atmosphere of the planet at sufficiently high temperatures and is characterized by developed turbulence. For realistic conditions the calculated fields of the complete set of parameters of the medium formed by the system of interacting supersonic exhaust jets of brake motors of the descent vehicle in the atmosphere of the planet are obtained. The parameters of the flow field in the most characteristic areas of the system of interacting jets are presented.
