The sensor is based on the PressureBased Non-Integer System Identification (NISIp) method for a transpiration cooled material. Here,<br>the pressure reading at the upstream side of the porous wall, the plenum, is used for the inverse<br>determination of surface heat flux. For this, the pressure impulse response and measurement accuracy<br>is found by laser calibration. Three sensors with equal design and geometry, but featuring different<br>porous materials, zirconium diboride, carbon\/carbon and copper, were investigated. The response time<br>of a carbon\/carbon sensor is significantly shorter than for the other materials. A maximum deviation<br>of 8% to 13% was found for the presented NISIp sensors. The experimental investigation of different<br>plenum volumes yields that the plenum volume has a damping effect on the temporal behaviour of the<br>plenum pressure<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-109.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-109.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Fabian Hufgard, Stefan Loehle, Hannah Boehrk, Matthew McGilvray, Johan Steelant, Stefanos Fasoulas<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-109<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1006,1014],"tags":[720,1085,1084,722,500],"class_list":["post-16139","post","type-post","status-publish","format-standard","hentry","category-events","category-hisst-2022","category-testing-and-evaluation-hisst-2022","tag-heat-flux-sensor","tag-nisip","tag-plenum-pressure","tag-porous-material","tag-transpiration-cooling","category-993","category-1006","category-1014","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16139","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16139"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16139\/revisions"}],"predecessor-version":[{"id":16140,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16139\/revisions\/16140"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16139"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16139"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16139"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
