To create a general impeller geometry in Bladegen it&#039;s necessary to input the meridional profile, blade angle distribution, and thickness distribution along the blade, so the program outputs the 3D geometry.<\/p>\n<p>How is the beta angle defined in this 2D coordinate system, named &quot;blade-to-blade view&quot;? (when it positive, negative?) I&acute;ve read that the beta is defined in the M&#039; vs theta, how does this 2D coordinate system relate to the real space (x, y, z) or its equivalent (r, theta, z) space? is there a conformational transformation preserving angles?<\/p>\n","protected":false},"template":"","class_list":["post-158143","topic","type-topic","status-closed","hentry","topic-tag-bladegen-1","topic-tag-cfd","topic-tag-cfx"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2514"],"_bbp_likes_count":["0"],"_bbp_subscription":["253568"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158143"],"_bbp_forum_id":["27792"],"_bbp_engagement":["68667","179458"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["177449"],"_bbp_last_active_id":["177449"],"_bbp_last_active_time":["2021-05-19 13:01:24"]},"test":"joaoalex"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158143","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\/158143\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158143"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
