“…Since blunt cone is an aerodynamic configuration existing extensively in hypersonic vehicle, it was chosen as the computing model in many studies on the receptivity characteristics of hypersonic boundary layer (Zhang et al 2008;Prakash et al 2011;Wan et al 2018). So, a blunt cone with 8° half-cone angle and 6 Mach freestream is introduced in this paper.…”

“…The receptivity in the presence of a shock has been investigated primarily using DNS in [49][50][51]62], among others, with the focus being primarily on the leading-edge adjustment. For the boundary layer over a cone, the DNS of the receptivity to acoustic waves suggest that the slow acoustic waves and entropy-layer disturbances after a bow shock play a key role for the excitation of first and second modes, respectively [63,64]. However, the precise scale tuning mechanisms are yet to be identified, which necessarily requires careful asymptotic analyses.…”
