Dear all,<\/p>\n

I Intend to simulate slurry flow that consists of air, water, and ore, so it will be three phase simulation in Ansys CFX. The phase modeling that I did was:<\/p>\n

    \n
  1. Water: Continuous fluid<\/li>\n
  2. Air: Continuous fluid<\/li>\n
  3. Ore: dispersed solid<\/li>\n<\/ol>\n

    I used in-homogeneous multiphase model (with standard free surface model) and homogeneous turbulence model. I want to simulate a steady-state simulations of the slurry fills a box with one inlet and several outlets (at first the box is filled with air only).<\/p>\n

    I faced a problem when I modeled the ore particle-particle interaction with kinetic theory. The problem that I faced was the simulation was not converging. It showed residuals that do not converge and go up and down very unstable. However, when I turn of the kinetic theory model, the result can be obtained and more stable (even though it did not converged to the residual target, but still stable than when I turn on the kinetic theory model).<\/p>\n

    I already read several journal regarding multiphase flow that involves solid, activating kinetic theory model is best for modeling particle-particle interactions.<\/p>\n

    Does anyone have suggestions to solve this problem?<\/p>\n

    Thank you very much.<\/p>\n","protected":false},"template":"","class_list":["post-304421","topic","type-topic","status-closed","hentry","topic-tag-ansys-cfx","topic-tag-eulerian-multiphase-model-1","topic-tag-multiphase-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["20011","39507","336310","199"],"_bbp_author_ip":["23.206.193.41"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1431"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["304421"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","20011","39507","336310"],"_bbp_voice_count":["4"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["343105"],"_bbp_last_active_id":["343105"],"_bbp_last_active_time":["2024-01-04 09:31:20"]},"test":"kireipicnic0723gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/304421","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\/304421\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=304421"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
