Hello,<\/p>\n

I have been trying to model the free surface response of a water body that is harmonically excited by a solid particle moving in the water domain using Harmonic Acoustics. <\/p>\n

I created a rectangular water body (70x17m) with the free surface and rigid wall BC. Inside the fluid body a solid steel particle (1x1x1m) is located with FSI and displacement BC. The solid particle has a displacement along the length (z-axis) of the basin and maintains a constant depth.<\/p>\n

<\/a> <\/p>\n

Apperently the elevation of the free surface (spatial patterns of the eigenmodes of the water body) can be displayed with directional deformation of the free surface and acoustic pressure of the water body. Analysing this and the frequency response graph it can be concluded that the spatial sloshing patterns and eigenfrequencies match up with the theory (Raichlen 1966). However, I am not sure how to interpret the amplitudes.<\/p>\n

 <\/p>\n

<\/a><\/p>\n

Firstly, I am interested if it makes sense to setup the model like this. Can the linear sloshing response of free surface under this type of harmonic forcing be modelled with Harmonic Acoustics? Or is the model schematized to bluntly?<\/p>\n

Secondly, I would like to know how to interpret the aplitudes of the free surface deformation. <\/p>\n

I would like to hear your opinion.<\/p>\n

Kind regards.<\/p>\n","protected":false},"template":"","class_list":["post-284206","topic","type-topic","status-closed","hentry","topic-tag-Eigenfrequencies-1","topic-tag-eigenmode","topic-tag-free-surface","topic-tag-fsi","topic-tag-harmonic-acoustics","topic-tag-sloshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["276568","240","58821","82304"],"_bbp_author_ip":["23.39.172.6"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1646"],"_edit_lock":["1684235613:207787"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["284206"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","58821","82304","276568"],"_bbp_voice_count":["4"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["292204"],"_bbp_last_active_id":["292204"],"_bbp_last_active_time":["2023-07-10 07:28:16"]},"test":"v-r-gallardotorrestudelft-nl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/284206","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\/284206\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=284206"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
