Polyflow ????: I hope you can assist me with some questions regarding my current project. In a melt channel, polypropylene flows through a rotating bolt with a transverse bore. The rotating bolt is rotatable and can be locked in four different positions at 10, 20, 30, and 45 degrees. At this point, I still need help in various areas:<\/span><\/p>\n

a) In the “Create a sub-task” section, the options for “Flow Problems” are available. For all choices, such as “Simplified Viscoelastic Non-Isothermal Flow Problems,” an error message occurs when reading the material, preventing the action from being executed. Question: Can only “Generalized Newtonian isothermal flow problem” be selected?<\/span><\/p>\n

 <\/span>b) My test material is “Virgin PP with MFR = 20 … 25 g\/10 min.” For example, the used material PP.513 has an MFR of 70 g\/10 min. Question: How can I adjust the MFR of the material?<\/span><\/p>\n

c) In the “Inflow calculation on Inleet” section, the volumetric flow rate is adjustable. The defined parameters do not match the results in the “Streamline” section. For example, selecting 0.5 m\/s shows 0.4 m\/s under “Velocities.” Question 1: How is this related? Question 2: Is it possible to set the temperature (450°C) of the plastic melt?<\/span><\/p>\n

 <\/span>d) To simulate the flow pattern, the “Fluid Wall” was created. Creating a semi-open rotating bolt, where one half is flowing through and the other half flows along the surface of the rotating bolt, does not work. (to simulate dead points, turbulence, and material wear) Question: Are only complete flows possible?<\/span><\/p>\n

 <\/span>e) A flawless flow pattern is displayed when there is a large flow entry from the melt channel into the transverse bore of the rotating bolt. However, with a narrow flow entry (i.e., 10°, 20°, and 30°), the simulation stops upon entering the transverse bore. Question: Is the simulation stopping due to the narrow flow passage?<\/span><\/p>\n

 <\/span>f) Is there a setting to simulate the temperature profile, i.e., the behavior of temperature during flow?<\/span><\/p>\n","protected":false},"template":"","class_list":["post-348001","topic","type-topic","status-closed","hentry","topic-tag-polyflow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["338157","852"],"_bbp_author_ip":["96.7.74.173"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["228"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["348001"],"_bbp_forum_id":["27792"],"_bbp_engagement":["852","338157"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["348761"],"_bbp_last_active_id":["348761"],"_bbp_last_active_time":["2024-02-04 07:19:00"]},"test":"braunfa81958th-nuernberg-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/348001","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\/348001\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=348001"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
