Careful Numerical Study of Flowfields about Symmetric External Conical Corners

Numerical study of flowfields about asymmetric external conical corners

“…Symmetrical departures from this configuration were presented in Ref. 3. For most cases discussed, plots of the cross-flow streamlines and isobar contours, similar to those in Fig.…”

“…For the present study, the values of 7 and M^ will be 1.4 and 3, respectively. These are the same values used in Ref, 3. The effect of Q on the flow is directly related to changes in the external angle $; and, as has already been mentioned, this determines the existence of a nodal or saddle point of streamlines when the cross flow stagnates at the corner.…”

“…3 it was shown that, as the corner radius was increased on a symmetrical configuration, the node-saddle-node structure was replaced with the single-node structure. For asymmetrical configurations, it is evident from Fig.…”

“…The bow shock wave was computed as a discontinuity satisfying the Rankine-Hugoniot equations, using the procedure described in Ref. 3.…”

“…. The timedependent Euler equations,(2)(3)(4)(5)(6), are written in the computational space (X, Y, T) defined byX= <t> 2 s i(Y}-<t> o-e w (X) e sk (x,T)-e w (…”
