Abstract
AbstractThe interfacial flow of two immiscible uniformly rotating micropolar and viscous fluid layers is investigated in this article. The top layer contains a micropolar fluid of having velocity components ), micro‐rotation components , density ρ1, viscosity μ1 and pressure p1 that is rotating with angular velocity ω1. A viscous fluid layer exists in the lower region with velocity components , density ρ2, viscosity μ2 and pressure p2 rotating with constant angular velocity ω2. The flow similarity solutions exist under the constraint , where (angular velocities ratio) and (densities ratio). The flow shows a co‐rotating case for and a counter‐rotating case for . A strong numerical technique known as the Keller‐box approach is utilized to obtain the solution of the resultant set of an ordinary differential equation. Similarity solutions can be found for (co‐rotating flows) but for (counter‐rotating flows), the similarity solution occurs up to the certain critical value of σ (i.e., ). Due to the coupling type of the flow near the liquid‐liquid interface, the micro polarity parameter K1 has an impact on both fluid's layer, even though the micropolar fluid exists just in the upper layer. The key objective of the current article is to analyze how these two different fluid layers will behave under the weak and strong concertation of microelements that can be fruitful in the engineering and scientific disciplines.
