The foundation of the Mars atmosphere is carbon dioxide and the behavior of imbalance at high temperatures in a hypersonic flight has not been correctly examined before. The scientists of the State University of St. Petersburg take into account the microscopic processes such as release of particles and release of CO molecules and also interaction with inert gases.
Experts for calculations developed their software codes. This made it possible to fully control the whole process – from theory to numerical modeling without using the third -party software.
It was revealed that the diffusion in carbon dioxide and for example helium mixture significantly affected heat transfer. Traditional calculations did not take into account this factor, so the heat flow indicators have almost doubled. The new model prevents such errors and increases reliability when calculating the conditions of the apparatus entering the Mars atmosphere.
