The hypersonic flow over double wedges has been studied extensively since it features a number of nonequilibrium flow phenomena that need to be carefully addressed in order to successfully design hypersonic and re-entry vehicles. With the particular attention to the system of shock waves that it is forme dover a double wedge, this project will aim at characterising the transition between different types of shock interaction as the freestream temperature is changed and therefore the physics involved with the flow changes. The project will study a set of different shock interference patterns with a flow that is typical of the Earth and/or Martian atmospheres and will aim at identifying values of freestream temeprature at which the transition from one interference type to another occur. Key objectives:

Perform a review study on the classification of shock interference patterns for air and/or CO2-based atmospheres; Perform an initial numerical study over a prescribed range of freestream temperatures to identify the existing different interaction types; Iteratively explore the range of temperatures to identify the values at which the transition from one type to another occurs up to a certain degree of accruacy in the temperature level.
