The multiphysics CFD software<br>STAR-CCM+ is used to perform a Conjugate Heat Transfer analysis on the aeroshell\u2019s faceted geometry.<br>Results are presented for four different geometry models tested in air at Mach 5 with angles of attack<br>\u03b1 = 0\u00b0, 5\u00b0 and 10\u00b0. The predicted surface heat transfer reveals areas of elevated heat loads at the ribs<br>between facets and at the aeroshell shoulder, due to local boundary layer thinning. The increase in<br>heat transfer at the ribs depends on the sharpness of the rib: more rounded shapes result in lower heat<br>fluxes. Comparison with high-speed wind tunnel tests shows good agreement with experimental data.<br>Stanton number and temperature profiles agree within 8% and 2% respectively. The discrepancies<br>between experiments and simulations are largest at the sharp ribs of the aeroshell. The sources of error<br>can be associated to three dimensional effects neglected in the heat flux derivations from temperature<br>measurements as well as experimental uncertaintes.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-395.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-395.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Pietro Innocenzi, Michela Gramola, Tom B.
