The conventional wisdom of speed in that day was to have tubular fuselages and an over all clean design but as transonic speeds were approached wave drag developed, then known only as a phenomena.
Whitcomb's aerodynamic breakthrough was referred to as the Transonic Area Rule.

A black hole accretion ﬂow being transonic, it must satisfy two sonic point conditions at the cost of one extra unknown, namely, the the sonic point.
Standing Shocks around Black Holes: An Analytical Study
When the transonic solutions are calculated later, we solve the differential equations for the radial four velocity ur and the angular momentum ℓ(= uφ ).
