“…Mixing is a process where solid, liquid, or gas molecules of a solution are in motion, moving from one location to another in a tank, chamber, or pipeline. Mixing methods are categorized as liquid–liquid, solid–liquid, gas–liquid, or a combination of all states such as solid–liquid–gas (Ohol and Vasuki 2020 ). The mixing process is completed when the solution becomes homogeneous or uniform, and non-uniformity in any form such as temperature, phase, concentration, colour, and viscosity are dispelled (Bowler et al 2020 ).…”

The present study introduces an active macroscopic mixing device for aqueous sanitizer preparation. It operates on a piezoelectrically actuated oscillating cantilever beam appropriate for disparate feature liquid–liquid mixing. A piezoelectric actuated cantilever beam at the third bending mode vibration frequency produces extreme vibrations when excited by a suitable voltage. Potent mixing occurs as the robust vibration energy is sent from the beam to the container’s test liquid. In this work, different glycerol concentrations were mixed with deionized (DI) water and ethanol at 25 ℃. The mixer’s performance to mix DI water–glycerol, ethanol–glycerol, and DI water–ethanol–glycerol considered a sanitizer was tested. The sanitizer mixture’s measured density, viscosity, and surface tension values were 0.7502 g cm −3 , 1.8906 cp, 34.7893 dyne cm −1 , respectively. The measured aqueous-based glycerol mixture’s density and viscosity values were validated with the computed values by previous researcher’s models and formulas. The observed density reading of the aqueous-based 25% glycerol concentration mixture agreed with the estimated value of a density model having ± 1.1290% deviation.
