Static pressure transducers were installed in the isolator<br>section, in order to measure the wall pressure of the isolator inflow. Eight different shock tunnel<br>conditions were tested in which the total enthalpy ranged from 950 to 2,150 kJ\/kg, resulting in a<br>variation of the incoming airflow rate from 390 to 660 g\/s. A semi-empirical correlation was preliminarily<br>proposed to estimate the air mass flow rate entering the model based on a linear regression fit with<br>coefficient of determination of 96% and residual differences less than 6%, showing to be a promising<br>path in the development of an air mass flow rate measurement system.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-153.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-153.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>L.
