As such, the use of computational simulations is vital in the design of Thermal Protection<br>Systems (TPSs) for hypersonic vehicles. Many TPSs use materials that ablate and this leads to changes<br>in shape of the body with time. As such, the computational mesh needs to be updated, whilst maintaining<br>a high resolution in the shock and boundary layer regions, which can require significant user input. In<br>this work, a prototype strand\/Cartesian Adaptive Mesh Refinement (CAMR) solver has been created using<br>the AMROC (Adaptive Mesh Refinement in Object\u00adoriented C++) framework, that enables meshes to be<br>generated with minimal user input. The strand\/CAMR technique combines a \u201cstrand\u201d mesh, grown from<br>a discretised surface, in the near\u00adbody region with an adaptive Cartesian mesh in the off\u00adbody region in<br>order to highly resolve off\u00adbody shocks and boundary layers. The development of the off\u00adbody and nearbody two\u00adtemperature Navier\u00adStokes solvers, and the overset algorithms used to join the two regions,<br>is described. A series of test cases that aim to verify and validate the hypersonic 2D\/axisymmetric<br>strand\/CAMR solver are presented. An order\u00adof\u00adaccruacy test is carried out on an overset domain to<br>verify the implementation of the new spatial\u00ad and time\u00adintegration methods. A high\u00adenthalpy experiment<br>is simulated in order to validate the new solver and investigate the influence of the overset mesh on heat<br>flux predictions. Finally, the automated surface deformation enabled by the new solver is demonstrated<br>through the simulation of a recessing nose\u00adtip. The results indicate that the strand\/CAMR technique can<br>be used to accurately simulate vehicles in hypersonic flows and offers a high level of automation.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-112.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-112.pdf\">Read the full paper ><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Chay W.
