Steady-state flow fields as a function of the longitudinal length x/L for the geometric (…) and thermal throat (- - -) choking cases obtained from the CFD solver. The steady Mach number ($\overline{\text{M}}$, (a)); the static pressure ($\overline{p}$, (b)) and the static temperature ($\overline{T}$, (c)) are displayed. Quantities are measured on the symmetry axis of the computational domain.
