4. SBLI in complex configurations
Ramjet and scramjet flowpaths are composed of several regions where SBLI are important. Mixed compression inlets and isolators exhibit a series of such interactions at different Mach numbers and boundary layer thicknesses. Fig. 12 shows some of the pertinent features in rectangular and circular cross-section devices. SBLI in the inlet regions generate separated flow in both configurations. The canonical double fin configuration of Fig. 1(f) discussed earlier in the context of Fig. 5 and Fig. 6 is highly pertinent in this regard: the main feature downstream is the low energy mushroom shaped region whose genesis is similar to that shown earlier in Fig. 5(c). This same feature is observed in the two very different scramjet flowpaths depicted in Fig. 12. There are many other features that arise in such flows on sidewalls and in corners, interactions with injection jets, flame devices and so on, whose description may be found for example in Refs. [142], [143], [144], [145], [146], [147] and [148].
