This study investigates the behavior of non-Newtonian fluids in hydrocyclones using computational fluid dynamics (CFD). Researchers analyze pressure, velocity, and viscosity patterns to understand particle behavior and fluid dynamics within hydrocyclones. Velocity profiles show how fluids and particles flow through the hydrocyclone, while pressure distributions indicate regions of high and low pressure, critical for separation efficiency. Viscosity fluctuations reveal the relationship between fluid rheology and flow dynamics, explaining how viscoelastic characteristics affect particle trajectories and separation efficiency. The goal is to optimize hydrocyclone design and operation to improve particle separation in viscoelastic food solutions, enhancing food processing technology and product quality. Researchers also examine the impact of geometric factors, such as hydrocyclone size and inlet configurations, and operating parameters like rotational speed and flow rate, on separation efficiency. By integrating complex analyses, researchers aim to develop a model that accurately predicts and optimizes hydrocyclone behavior, improving process control and food quality. Hydrocyclones are devices used to separate particles or liquids from fluid streams. They are used in various industrial applications, including water treatment, food processing, and petroleum extraction. Hydrocyclones are preferred over centrifuges due to their low operating costs and lack of rotating parts. Fluid velocity inside hydrocyclones is turbulent and whirling, causing particles of different sizes, shapes, and densities to separate. Hydrocyclones have two exits: underflow and overflow. The underflow contains heavier, larger particles, while the overflow contains smaller particles or cleaner fluid. Hydrocyclones are adaptable, efficient, and can handle clustered solids or thixotropic liquids. However, they have limitations, such as restricted separation capacity, erosion, and lower resolution compared to other separation methods. The separation efficiency of hydrocyclones is defined as the volumetric ratio of particles in the underflow to those fed into the hydrocyclone. The slip ratio is the volume of suspension in the underflow to that collected from both overflow and underflow. Solid recovery is calculated as the ratio of the mass flow rate of solid particles in the underflow to that in the feed. The concentration ratio is the ratio of the concentration of particles in the underflow to that in the feed. Particle purity and yield are defined as the ratio of the partition number of a particular particle size to that of others, expressed as a percentage. Hydrocyclone separation mechanisms include primary and secondary vortices, and an air core. The primary vortex carries denser particles to the underflow, while the secondary vortex carries lighter particles to the overflow. Air core formation is inevitable in hydrocyclones and affects separation efficiency. The geometry of hydrocyclones, such as vortex finder diameter, depth, and underflow diameter, significantly influences separation efficiency. Fluid velocity distribution within hydrocyclones includes axial, tangential, and radial components, with tangential velocity being crucial for particle separation.
