An unsteady sliding mesh approach was used to simulate the impeller rotation. The flow field, solids hold-up and power consumptions were investigated in the solid-liquid mixing system. Compared to the standard Intermig impeller, the improved Intermig impeller coupled with the special sloped baffle could promote the fluid circulation, creating better solid suspension and consuming lesser power. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:CFD; stirred tank; solids suspension; mixing; improved Intermig impeller KeyWords Plus:SUSPENSION; REGIME ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Zhao, HL (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ Northeastern Univ, Minist Educ, Key Lab Ecol Utilizat Multimet Intergrown Ores, Shenyang 100819, Peoples R China. µØÖ·: ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 1 ] Northeastern Univ, Minist Educ, Key Lab Ecol Utilizat Multimet Intergrown Ores, Shenyang 100819, Peoples R China ³ö°æÉÌ AMER INST PHYSICS, 2 HUNTINGTON QUADRANGLE, STE 1NO1, MELVILLE, NY 11747-4501 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò:Science & Technology - Other Topics; Materials Science; Physics Web of Science Àà±ð:Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; Physics, Applied ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ roceedings PaperÓïÖÖ:English Èë²ØºÅ: WOS:000321003200317 ISBN:978-0-7354-1166-1 ISSN: 0094-243X ÆäËûÐÅÏ¢ IDS ºÅ: BFQ84 Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 11 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 1 |
