Hello, dear committee,<\/span>
To control the recirculation zone at a diverging channel, backward-facing step geometry. I used a synthetic jet where his position is in this stage.<\/span>
I found in publications that 30 periods were used for the blowing-suction of this jet and that I had also respected this condition. My problem is that in this publication, the synthetic jet takes only 0.1s so that the results converge around a gain of -24% over the distance.<\/span>
the initial attachment after this gain has remained fixed. Contrary to my situation, I find that the response time of my plane is too long close to 0.3 s and that the gain always increases. I averaged the CF after each period.<\/span>
Do you have an idea to solve this problem?<\/span><\/p>\n","protected":false},"template":"","class_list":["post-36645","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["8817"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0"],"_btv_view_count":["243"],"_bbp_subscription":["237699"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["36645"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","159999"],"_bbp_voice_count":["3"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["90227"],"_bbp_last_active_id":["90227"],"_bbp_last_active_time":["2019-07-23 10:44:42"]},"test":"abd-fs"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/36645","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/36645\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=36645"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
