According to my understanding, the Swirl RPM provides the swirl to the flow emanating from the fan. So, If I put the Swirl RPM value zero, then the flow coming out of the fan will be straight. If I put the swirl RPM to the rated RPM (I am not sure what value I should put for creating the swirl, so I am using the rated RPM of the fan), then the flow will be swirled. But setting these two extreme values of swirl RPM, i.e., 0RPM and 3075 RPM, the flow velocity in the post-processing results is different and does not make any sense. When I put the swirl RPM to 3075 and my operating RPM to 10, the flow velocity in the post-processing field overlay is 0.2077 max (attached figure). but when I put the swirl RPM to 0 and operating RPM to 10 the flow velocity is very high (attached figure). According to my understanding of the Swirl RPM, it does not make sense. I would like someone to help me with this.&nbsp;<\/p>\n<p>Please let me know if you need any further information from me. <a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708110156-Capture1112.PNG\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708110156-Capture1112.PNG\" alt=\"\"><\/a> Figure1 having Swirl RPM<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708110297-Capture111211.PNG\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708110297-Capture111211.PNG\" alt=\"\"><\/a><\/p>\n","protected":false},"template":"","class_list":["post-352065","topic","type-topic","status-closed","hentry","topic-tag-AEDTICEPAK-1","topic-tag-fan","topic-tag-intake-fan","topic-tag-swirl-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["64787","35359"],"_bbp_author_ip":["23.206.193.59"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["710"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1708110389:187056"],"_bbp_topic_id":["352065"],"_bbp_forum_id":["27793"],"_bbp_engagement":["35359","64787"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["352473"],"_bbp_last_active_id":["352473"],"_bbp_last_active_time":["2024-02-20 09:39:48"]},"test":"sgillanncsu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/352065","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/352065\/revisions"}],"predecessor-version":[{"id":352066,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/352065\/revisions\/352066"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=352065"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
