This keyword will help you establish your first case about H2-air detonation and structural response based on CESE-chemistry-structure coupling method in LS-DYNA. Meshes are very coarse, so the results are not reasonable compared to any real situation. <\/p>\n\n\n\n

The CESE-chemistry coupling method incorporates chemical kinetics within a compressible flow framework and can be fully integrated with the structural solver in LS-DYNA. It provides high precision for the prediction of structural response subjected to reactive gas explosion. For more information, please refer to Chen, D., Wu, C., & Li, J. (2023).

This handbook has been written as a part of Christian Michelsen Research’s (CMR) research programme “Gas Safety Programme 1990-1992” (GSP90-92). The participants of the programme are: BP Norway Limited U.A., Bundesministerium f\u00fcr Forschung und Technologie, Conoco Norway Inc., Elf Petroleum Norge A\/S, Esso Norge A\/S, Gaz de France, Health and Safety Executive, Mobil Exploration Norway Inc., Norsk Hydro, Norwegian Petroleum Directorate, N.V. Nederlandse Gasunie, Phillips Petroleum Company Norway and Statoil.
The purpose of this handbook is to give a brief introduction to gas explosion safety, based on our current knowledge of the subject and on our experience in applying this knowledge to practical problems in the industry. Because of the intended brevity and simplicity of the handbook the information provided may in some cases be strongly simplified and\/or incomplete. For in-depth information on the various subjects the reader is referred to the literature described in the References.
The user of this handbook is intended to be a process-, design- or structural engineer, but the handbook should also be useful for safety engineers.<\/p>\n<\/details>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_analysis_target_kw":"","footnotes":""},"class_list":["post-23","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/pages\/23","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/comments?post=23"}],"version-history":[{"count":71,"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/pages\/23\/revisions"}],"predecessor-version":[{"id":357,"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/pages\/23\/revisions\/357"}],"wp:attachment":[{"href":"https:\/\/www.dichen-safe.tech\/index.php\/wp-json\/wp\/v2\/media?parent=23"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
