Abstract
A three-temperature model was used to study the wake of a conic at hypersonic velocities and angle of attack. Eight cases were considered: four angles of attack, ranging from 0 degrees to 30 degrees, and two altitudes, 40 km and 50 km. The velocity for all cases was 5 km/s. The complex structure of the wake was characterized by large regions of thermal inversions and an abundance of free-electrons; both of which persisted far downstream and increased with angle of attack. The electron temperature was largely in a state of non-equilibrium from the vibrational temperature suggesting that the added degree of freedom of the three-temperature model, over the two-temperature, increases the fidelity of the simulation.
