Abstract:Coherent small-amplitude unsteadiness of the shock wave and the separation region over a canonical double cone flow, termed in literature as oscillation-type unsteadiness, is experimentally studied at Mach 6. The double cone model is defined by three non-dimensional geometric parameters: fore- and aft-cone angles (
$\theta _1$
and
$\theta _2$
), and ratio of the conical slant lengths (
$\varLambda$
). Previous studies of oscillatio… Show more
