Euler Euler\u2019s two-phase flow model is established. The flow field in the combined structure granulation chamber with different layout is simulated. The volume distribution and velocity field change of Si3N4 particles in the combined structure granulation chamber with different layout are analyzed. The results show that the angle between two adjacent composite structures is 20\u2218, 60\u2218, 80\u2218 and completely standard the Si3N4 particles with volume fraction index greater than 0.8 account for 10.2%, 11.5%, 12.5% and 6.7% of the total volume respectively. When the combined structure is completely standard, several small convolutions are found. The whirling phenomenon in the granulation chamber is improved. When the angle between two adjacent composite structures is 20\u2218, 60\u2218, 80\u2218 and complete standard, the proportion of qualified particles is 59%, 64%, 66% and 68%. The fluidity index is 84, 85, 87 and 88, respectively. To sum up, the combination structure of the granulation chamber is a complete standard, it is beneficial to improve the spin phenomenon of Si3N4 particles in the granulation chamber.<\/jats:p>","DOI":"10.3233\/jcm-204664","type":"journal-article","created":{"date-parts":[[2020,10,2]],"date-time":"2020-10-02T13:57:42Z","timestamp":1601647062000},"page":"449-460","source":"Crossref","is-referenced-by-count":0,"title":["Analysis
