Various impeller designs including conventional and new impeller designs were employed to cover both radial and axial flow impellers. The microscopic method associated with image processing tools was used for the drop size analysis. The results showed the hydrofoil impeller produced the largest drop sizes while the double-curved blade turbine produced the smallest drop sizes, corresponding to about 37% difference. Increasing the dispersed phase volume ratio from 1% to 10%) increased the d32 by approximately 20–40%. Adaptive neuro-fuzzy inference system based on fuzzy C–means (ANFIS-FCM) clustering algorithm was used to develop a model to predict drop sizes, and its validation and accuracy were examined by comparing the results to the experimental data. The results also proved the superior prediction capability of the ANFIS-FCM method over the empirical correlations for the most cases. date: 2019-07 date_type: published publisher: ELSEVIER SCIENCE BV official_url: https://doi.org/10.1016/j.jtice.2019.04.005 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1673401 doi: 10.1016/j.jtice.2019.04.005 lyricists_name: Abbasi, Mohammad Reza lyricists_id: MRABB39 actors_name: Abbasi, Mohammad Reza actors_id: MRABB39 actors_role: owner full_text_status: public publication: Journal of the Taiwan Institute of Chemical Engineers volume: 100 pagerange: 26-36 pages: 11 citation: Ghotli, RA; Abbasi, MR; Bagheri, A; Raman, AAA; Ibrahim, S; Bostanci, H; (2019) Experimental and modeling evaluation of droplet size in immiscible liquid-liquid stirred vessel using various impeller designs.
