Abstract

Investigating glycerin-water mixing dynamics in a vertical container with variable velocities is crucial for optimising industrial processes and understanding fluid behavior in diverse applications. Despite having several studies in the open literature that discussed the electrical and physical properties of glycerol/water mixtures, this study specifically investigates the dynamic interactions of glycerin-water mixing in a vertical container with variable water and glycerin intake velocities using ANSYS fluent v.16.1, to evaluate the associated spatial distribution inside the container. When glycerin and water are mixed, the combination form is a homogenous solution. The optimal glycerin-to-water ratio is conditional on the application at hand. At a mixing speed of 0.1 m/s, glycerin and water exhibit a phenomenon in which the glycerin collects on one side of the container while the water stays put on the other side. The density difference between the two substances accounts for the observed separation. The velocity curves slow down as the fluids disperse inside the container, but the increased density of the glycerin side causes it to slow down even more. When the glycerin's velocity is increased to 0.2 m/s, the behavior of mixture changes, resulting in the displacement of water and the appearance of a brush-like shape. It is recommended to conduct a specific research to investigate essential factors like temperature, additives to improve the practical applications of glycerin-water mixing.
