Particulates penetrating into the boundary-layer flow can excite wavepackets of the first and\/or second mode instability. These disturbances grow downstream, reach the threshold amplitude and ultimately break down to turbulent spots. A numerical model is developed to simulate excitation of unstable wavepackets by spherical solid particulates. As an example, computations are carried out for a 14\u00b0 half-angle sharp wedge flying at altitude 20 km, Mach number 4 and zero angle of attack. The numerical results agree satisfactory with the theory developed by Fedorov [1]. The numerical model opens up an opportunity to investigate receptivity to particulates for practical supersonic and hypersonic configurations such as blunt bodies of revolution and wings.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><a href=\"https:\/\/www.cambridge.org\/core\/journals\/journal-of-fluid-mechanics\/article\/receptivity-of-a-supersonic-boundary-layer-to-solid-particulates\/452C3E0AFD181F4C22FD53FAE96701B0\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_1440832.pdf\">Download the Full Paper from the Cambridge website &gt;<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Pavel V.
