We present a framework to quantitatively describe energy exchange in high-speed turbulent
flows, also including the hypersonic regime. Governing equations are introduced which
control the transport of the mean-field kinetic energy (km), the turbulence kinetic energy (kt),
the mean-field internal energy (em), and the turbulence internal energy (et). The common
terms in the transport equations are found to represent energy exchanges and interactions
among km, kt, em, and et. The routes of energy exchange are then highlighted and …
