1D Turbulent Heating
We consider here the evolution of a 1D spectrum in the expanding (radial) wind, that is, with wavevectors all aligned in a given direction. We consider two cases: wavevectors in the radial direction, and wavevectors in a transverse direction (perpendicular to the radial). Based on these assumptions, we present a model of turbulent heating that is then compared to direct numerical simulations of Hydrodynamic turbulence in 1D.
