Plot of the polar density a), the dimensionless polar pressure b) and the polar temperature c) for the oscillating solution. The temperature is the effective one as in Fig. 3. The polar effective temperature is fairly constant along the jet, suggesting a uniform level of turbulence. The three extra asymptotic curves in c) correspond to three possible values of the temperature at infinity, obtained by subtracting non-zero values of the pressure at infinity, as shown in b).
