The aim of the collaborative research center is an enormous\u00a0reduction of non metallic inclusions in the metal matrix by utilizing intelligent \ufb01lter materials as well as \ufb01lter\u00a0systems with a functionalized \ufb01lter surface. More than 60 scientists from 12 different disciplines in the areas of\u00a0ceramics, processing, \ufb01ltration simulation, metal casting, metal testing, \ufb02ow dynamics, modeling of ceramic\u00a0behavior at elevated temperatures and thermodynamics work for the next four years.\u00a0It is essential to know thermophysical properties of the open celled ceramic foams and to determine heat\u00a0transfer coef\ufb01cient during the \ufb01ltration process to achieve the objectives in one of the areas mentioned above.\u00a0Particularly the transient \ufb01ltration process is of vital importance for the thermomechanical behavior of the \ufb01lters.\u00a0Associated with its extremely large temperature rise, large amounts of heat are transfered within seconds. In\u00a0addition to measurements in the casting process, numerical evaluation of the obtained temperature curves\u00a0is necessary. The conservation equations describing the system have to be solved for the determination of\u00a0the volumetric heat transfer coef\ufb01cients. The international PhD-candidate will be integrated in subproject\u00a0B03 of the CRC at the chair of Engineering Thermodynamics and contribute to the numerical part of this\u00a0project.<\/p>\n<p style=\"text-align: justify;\">Deadline: March 31st, 2012<\/p>\n<p style=\"text-align: justify;\">For details:\u00a0<a href=\"https:\/\/africa-and-science.com\/wp-content\/uploads\/2012\/02\/International-Scholarship-for-PhD-Students-Univ-Freiberg.pdf\">International Scholarship for PhD-Students- Univ Freiberg<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00ab\u00a0\u2018Multi-Functional Filters for Metal Melt Filtration &#8211; A Contribution\u00a0towards Zero Defect Materials\u00a0\u00bb\u2018 There exists an increasing pressure on the metal-making and metal using industry to remove solid and liquid\u00a0inclusions such as deoxidation products, sul\ufb01des, nitrides carbides etc. and thereby improve metal cleanliness.\u00a0It is well known that size, type and distribution of non-metallic inclusions in metal [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[18],"tags":[],"class_list":["post-2582","post","type-post","status-publish","format-standard","hentry","category-scholarship-bourses"],"_links":{"self":[{"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/posts\/2582"}],"collection":[{"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2582"}],"version-history":[{"count":4,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/posts\/2582\/revisions"}],"predecessor-version":[{"id":2630,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=\/wp\/v2\/posts\/2582\/revisions\/2630"}],"wp:attachment":[{"href":"https:\/\/africa-and-science.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2582"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2582"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/africa-and-science.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2582"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
