“…The tiny size nanoparticles are useful to carry the slip velocity within the partcles of conventional fluids [9]. Various researchers have shown that particle rotation is also vital for the enhancement of heat transfer coefficient [10][11][12][13]. Due to the slip velocity of nanoparticles with the base fluid molecules, there is a possibility of microrotation in addition to the translation.…”

Nanofluid comprises nanoparticles that have varied applications in several industries as well as science and engineering due to their heavier thermal conductivity in comparison to conventional fluids. In such applications the role of transportation is vital. However, biomedical applications such as the flow of blood in the human body, peristaltic pumping, processes, etc. the use of nanofluid are important. Therefore, the present investigation aims at the enhancement of thermophysical properties on the radiative micropolar nanofluid flow past a permeable moving surface. These physical properties are studied incorporating the concept of Koo-Kleinsteuer-Li (KKL) model. The crux of the study is the approximate analytical technique, that is, the Homotopy Perturbation Method (HPM). The illustration of the contributing parameters on the flow phenomena is obtained via graphical as well as tabular form. A comparative study is carried out for the good agreement of the present result with an earlier established result in a particular case. Some important findings of this work are a retardation in the linear velocity profile is observed due to increase in the volume fraction of the particle. Suction slows down the linear velocity profile whereas the impact is counter productive in case of injection. A hike in the angular velocity profile is seen in case of greater suction whereas the opposite effect is observed for injection. An increase in the thermal radiation boosts up the fluid temperature and as a result of this an increase in thermal layer thickness is observed.

In the paper, an analysis is performed to study the unsteady behaviour of micropolar fluid under mixed convection and mass transfer. In the process of study, similarity transformational approach has been considered under variable viscosity and thermal conductivity. Governing equations for the problem concerned are developed under prescribed constraints and latter on numerically solved by using Runge-Kutta method. The residual graphs represent various important parameters of the problem, viz., velocity, temperature, microrotation, concentration of the fluid and also considered the effects of Soret and Dufour within the boundary layers and analyzed.

The quest to efficiently manage heat generation/absorption in industries, such as chemical production, mechanical machines, oil exploration, and aeronautical engineering, is in high demand. This study is conducted to examine the impacts of internal heat generation/absorption as well as unsteady mixed convection of the micropolar fluid through a permeable channel. The formulated nonlinear fundamental equations converted from partial differential equation to ordinary differential equation are numerically analyzed and solved using the Laguerre Collocation Method along with Gauss–Lobatto points. To verify the simulation's accuracy, validation is performed via shooting technique with the fourth‐order Runge–Kutta method acting as the control method with the aid of Mathematica 11.0 software. The behavior of the flow was influenced by various physical parameters, which were analyzed using plots and tables. Impacts of skin friction, Sherwood number, and Nusselt number are evaluated. The findings reveal that an improvement in the micropolar term leads to an enhancement in temperature and velocity while angular momentum declines. Additionally, it was revealed that an increase in nonuniform heat generation parameters, magnetic term, and Eckert number improves the temperature profile, while the greater Grashof number results in an enhancement in the velocity profile.
