Favorable comparisons which have been obtained with the separated flow data of Kooi (M∞ = 1.4) demonstrate that the present procedure is capable of accurately resolving many of the details of transonic shock-wave, boundary-layer interaction. Second, the results show that the effect of displacement thickness interaction dominates over the effects produced by normal pressure gradients and imbedded shocks for transonic shock induced separated flows. Calculations made with an improved algebraic turbulence model demonstrate that the computed results are more sensitive to the turbulence model than to whether or not normal pressure gradients are included in the analysis. Incorporation of a windward differencing scheme in an airfoil transitional bubble analysis has demonstrated that the FLARE approximation is accurate even for large reversed flow velocities. However, use of a wind ward differencing scheme has revealed the existence of a new counterrotating bubble structure in the separated flow region.
