Notes. turb2 is the more turbulent model so we doubled its horizontal resolution to ensure that the fluid motions are well resolved. When it is convenient, we distinguish between convection zone (CZ) and radiative zone (RZ). Pr = ν/κ is the Prantdl number, Re = VL/ν the Reynolds number where L = 0.97 R⊙ and V is the rms convective velocity.
