A study was done to investigate effect of volume ratio of water and used cooking oil to the characteristic of Taylor-Couette flow in terms of shear stress and energy loss distribution within Taylor-Couette column. The characterisation study was carried out by applying water and waste cooking oil at volume ratio of 1:1, 1:3, 1:5, and 1:6. The inner cylinder was rotated at 300 rpm while the outer cylinder was kept static. It was found that optimal volume ratio for wastewater treatment was 1:1, shown by the phenomenon of Modulated Wavy Vortices flow regime. The highest Taylor number of 1.01x107was also achieved in the volume ratio, while the shear stress was -1.99. © 2021. All Rights Reserved.
