Detailed Description

Per-cell stable time step for CFL = 1 (Blazek eqs. 6.20-6.21, C = 4): dt_i = 2 V_i / (sum_f (|u_n| + a)_f A_f + 4 nu_eff sum_f A_f^2 / V_i), with the face wave speed taken as the max over the two adjacent cells and nu_eff = max(4/3, gamma/Pr) mu / rho for viscous flow. Half the sums over faces stand for Blazek's sums of projected areas.
