A free-piston Stirling convertor is a candidate technology that is considered an efficient and reliable power conversion device for such purposes. While already very efficient, it is believed that better Stirling engines can be developed if the losses inherent its current designs could be better understood. However, they are difficult to instrument and so efforts are underway to simulate a complete Stirling engine numerically. This has only recently been attempted and a review of the methods leading up to and including such computational analysis is presented. And finally it is proposed that the quality and depth of Stirling loss understanding may be improved by utilizing the higher fidelity and efficiency of recently developed numerical methods. One such method, the Ultra HI-Fl technique is presented in detail.","isLessonsLearned":false,"disseminated":"DOCUMENT_AND_METADATA","meetings":[{"submissionId":20040171934,"name":"American Inst. of Aeronautics and Astronautics","location":"United States","id":"07da002588d64aa897e0d513f455930f"},{"country":"United States","submissionId":20040171934,"endDate":"2004-08-19T00:00:00.0000000+00:00","sponsors":[{"meta":{"organization":{"name":"American Inst. of Aeronautics and Astronautics","location":"United States"}},"meetingId":"c350026aebb24e30b7a237b68bd45779","id":"bd25e6000d964678a229859fc94ce63b"}],"name":"Second International Energy Conversion Engineering Conference","location":"Providence, RI","id":"c350026aebb24e30b7a237b68bd45779","startDate":"2004-08-16T00:00:00.0000000+00:00"}],"publications":[{"submissionId":20040171934,"id":"7b7654565a6742299b265078f8a96155","publicationDate":"2004-10-01T00:00:00.0000000+00:00"}],"status":"CURATED","related":[],"downloads":[{"draft":false,"mimetype":"application/pdf","name":"20040171934.pdf","type":"STI","links":{"original":"/api/citations/20040171934/downloads/20040171934.pdf","pdf":"/api/citations/20040171934/downloads/20040171934.pdf","fulltext":"/api/citations/20040171934/downloads/20040171934.txt"}}],"downloadsAvailable":true,"index":"submissions-2026-05-07-04-55"}
