It is the structure that\ngives the metal foams the characteristics that make them well suited for many\napplication including heat exchangers. In this work, the structure of open\ncelled metal foams is quantitatively characterized using an image analysis\nbased method in order to predict the evaporative heat transfer of the metal\nfoam using the fluid permeability. Several image processing algorithms were\ndeveloped to quantitatively characterize the porosity, surface area per unit\nvolume and the tortousity of metal foams from digital images of the cross\nsections of the material, and an expression was used to calculate the fluid\npermeability. An algorithm was developed to partion the pore space in the\ndigital images so that individual cells within the structure\u0026nbsp; could also be quantitatively\ncharacterized.\u0026nbsp; Tools were also developed\nto predict the structure of open celled foam processed using the sacrificial\ntemplate method by digitally constructing microstructures based the particle\npacking of the sacrificial templating material.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"MSE MS Defense - Stephanie Lin"}],"uid":"27388","created_gmt":"2010-10-26 07:50:58","changed_gmt":"2016-10-08 01:53:16","author":"Bill Miller","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-11-03T12:00:00-04:00","event_time_end":"2010-11-03T13:00:00-04:00","event_time_end_last":"2010-11-03T13:00:00-04:00","gmt_time_start":"2010-11-03 16:00:00","gmt_time_end":"2010-11-03 17:00:00","gmt_time_end_last":"2010-11-03 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1238","name":"School of Materials Science and Engineering"}],"categories":[],"keywords":[{"id":"10802","name":"MSE_Interal_Event"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
