MICROPOLAR FLUIDS PROPERTIES AND APPLICATIONS IN ENGINEERING AND SCIENCE

Abstract

This paper presents an analysis of micropolar fluid past a wedge, considering the effects of viscous dissipation and heat absorption for flow systems doped with gyrotactic microorganisms. The transport model developed using nonlinear PDEs was transformed into a set of equivalent ODEs through suitable transformation equations. The shooting technique in micropolar fluid, in conjunction with the Runge-Kutta-Fehlberg integration scheme in microorganisms, was used to solve the obtained set of equations numerically. The effects of key factors on non-dimensional momentum profiles, temperature, and motile bioconvective Lewis microorganism density were estimated for the impact of pressure gradient parameter, Eckert number, material parameter, heat sink, and bioconvection Lewis number. The numerical data obtained was graphically presented, and the consequences of the major factors were thoroughly described in both the cases of Blasius and stagnation flow. Micropolar fluid is a type of fluid that displays microscopic impacts due to the phenomenon of fluid particle micromotion. The effectiveness of liquid crystals, lubricants, animal blood flowing through rigid cells, and other substances can be discussed using micropolar fluids. The unique feature of this fluid class is couple stress sustenance. This study is important for understanding the behaviour of micropolar fluids and can be applied in various fields, such as lubricants, cooling of metal plates in a bath tub, animal’s blood, and physiological fluids, among other things. The numerical data obtained in this study provides new insights into the behaviour of micropolar fluids and can serve as a basis for further research in this field. Overall, this study provides valuable insights into the properties and applications of micropolar fluids in engineering and science.
