Comparative Analysis of Electrorheological and Magnetorheological Fluids in the Design and Optimization of Micropumps

Abstract

This research introduces the fundamental concepts of electrorheological (ER) and magnetorheological (MR) fluids, highlighting their unique rheological properties, which can be controlled by an external electric or magnetic field. The study emphasizes the potential of harnessing these fluids in micropump design. It also explores the diverse applications of micropumps in various fields and stresses the significance of optimizing their performance through the incorporation of ER and MR fluids due to their tunable viscosity characteristics. The core of the research involves a comprehensive comparative analysis of ER and MR fluids, delving into their rheological behavior under varying electric and magnetic fields, considering factors like viscosity, shear stress, and response time. Experimental data and mathematical models are used to provide a detailed understanding of their behavior. Building upon this analysis, the study explores the integration of ER and MR fluids into micropump design, addressing parameters influencing pump performance and employing optimization techniques. The research concludes by discussing practical implications, potential advantages, and challenges associated with the use of these rheological fluids in micropumps and outlines future research directions to advance the field of micropump technology with rheological fluids.
