These are multiscale\/multiphysics complex flow phenomena. To solve these phenomena, a more comprehensive understanding of turbulence physics is important. By developing reliable and effective methods for direct numerical simulations (DNSs) of the Navier-Stokes equations and performing large-scale DNSs of turbulence using supercomputers, we are studying turbulence physics for various complex flow phenomena.<\/p>\n<\/div>\n<div><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-816\" src=\"http:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2019\/08\/_\u56f31-e1564986468617.jpg\" alt=\"\" width=\"170\" height=\"288\" \/> Cluster structure of high voricity regions in high Reynolds number turbulence obtained by large-scale DNS<\/div>\n<\/div>\n<hr \/>\n<h2>Mathematical and scientific information reduction and visualization of large-scale time seri<\/h2>\n<div class=\"columns\">\n<div><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-815\" src=\"http:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2019\/08\/_\u56f3\uff12-e1564986450200.jpg\" alt=\"\" width=\"170\" height=\"304\" \/> A scalar field and its persistent diagram<\/div>\n<div>\n<p>A method for efficiently extracting important information from huge time series datasets obtained from large-scale numerical simulations is required. Flow visualization and analysis of conditional statistics are effective for understanding turbulence phenomena. Persistent homology analysis enables us to systematically extract remarkable &#8220;changes&#8221; in the spatio-temporal space of a scalar field. By combining these, we are developing methods for detecting and understanding important events in complex turbulent flow phenomena.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Research Area : Numerical Analysis of Flow Phenomena Prof. ISHIHARA Takashi &gt;&gt;&gt; website Computational science of multiscale\/multiphysics comp &hellip; <a href=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/research\/department-of-human-ecology\/applied-numerical-analysis\"> read more&#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":117,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"research.php","meta":{"footnotes":""},"class_list":["post-806","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/806"}],"collection":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/comments?post=806"}],"version-history":[{"count":33,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/806\/revisions"}],"predecessor-version":[{"id":2406,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/806\/revisions\/2406"}],"up":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/117"}],"wp:attachment":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/media?parent=806"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
