Achieving prototypical\u0026nbsp;steady-state incident heat fluxes of 10 MW\/m2 in a lab-scale\u0026nbsp;remains a major challenge.\u0026nbsp;As an alternative to heating the test\u0026nbsp;section, this work presents an initial assessment of a\u0026nbsp;\u0026ldquo;reversed heat flux approach\u0026rdquo;, pioneered by the Karlsruhe\u0026nbsp;Institute of Technology (KIT), that cools the test modules\u0026nbsp;(instead of heating them) with water to determine the heat\u0026nbsp;transfer coefficients (HTC).\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe objectives of this design study are to: \u0026nbsp;1) determine whether\u0026nbsp;such a reversed heat flux approach can be used to experimentally\u0026nbsp;study the thermal-hydraulic performance of helium-cooled divertor\u0026nbsp;concepts, and 2) determine the design and operational parameters\u0026nbsp;for a small-scale submerged water jet impingement cooling\u0026nbsp;facility suitable for validating these numerical predictions.\u0026nbsp;Numerical simulations were performed suggesting that a submerged\u0026nbsp;single-phase impinging water jet at (300 K, 1 MPa) and \u0026nbsp;= 3.5\u0026nbsp;kg\/s can remove heat fluxes as great as 7.5 MW\/m2 over a 2 cm\u0026nbsp;diameter area and a water cooling facility to accompany the\u0026nbsp;current GT helium loop was designed based on these predictions.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMark your calendar to join us for the Heat Lab\u0026rsquo;s\u0026nbsp;upcoming Thermal Science Seminar.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Mark your calendar to join us for the Heat Lab\u2019s\u00a0upcoming Thermal Science Seminar."}],"uid":"27469","created_gmt":"2017-03-08 15:02:01","changed_gmt":"2017-04-13 21:12:27","author":"Kristen Bailey","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-03-15T17:30:00-04:00","event_time_end":"2017-03-15T18:30:00-04:00","event_time_end_last":"2017-03-15T18:30:00-04:00","gmt_time_start":"2017-03-15 21:30:00","gmt_time_end":"2017-03-15 22:30:00","gmt_time_end_last":"2017-03-15 22:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"108731","name":"School of Mechanical Engineering"},{"id":"1182","name":"General"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"},{"id":"1791","name":"Student sponsored"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:courtney.aiken@me.gatech.edu\u0022\u003ECourtney Aiken\u003C\/a\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
