The current study focuses on the laminar flow of copper and copper oxide ($${\text{Cu/blood}}$$ Cu/blood and $${\text{Cu}} + {\text{CuO/blood}}$$ Cu + CuO/blood ) hybrid nanoliquid, considering blood as a carrier fluid in a rectangular domain between two permeable channels. This study may manipulate for the purpose such as the drug delivery process, flow dynamic mechanism of the micro-circulatory system. In the proposed model, MHD and heat source/sink on the flow pattern have been studied. Furthermore, the sides of each channel are permeable, allowing the nanoliquid to escape, filter, squeezing and dilating with a fixed velocity. Appropriate transformations are incorporated to convert the governing partial differential equations and the boundary conditions suitable for computation. The elegant homotopy analysis method (HAM) is used to obtain analytic approximations for the resulting system of nonlinear differential equations. The features of flow characteristics such as velocity, and temperature profiles in response to the variations of the emerging parameters are simulated and examined with a physical explanation. The magnetic field plays a vital role in the blood flow and therefore the existing literature has been extending with the addition of magnetic field. Among the many outputs of the study, it is found that the pressure distribution decline with the accumulated values of the magnetic parameter at the center of the flow regime. The augmentation in the temperature distribution estimates the pH values and electric conductivity. Therefore, the $${\text{Cu}}\,\,{\text{and}}\,\,{\text{CuO}}$$ Cu and CuO hybrid nanofluids are used in this study for medication purposes. The magnetic field has an important role in the blood flow and therefore the extending study has been extending using the magnetic field. The heat emission/absorption term is added to the energy equation to maintain the homogeneous temperature for the blood flow. We expect that this work will provide efficient outputs for medical purposes such as drug delivery.
The combined effects of magnetic and electrohydrodynamic on the water-based iron oxide and CNTs hybrid nanoliquids flow between two rotating plates are examined. The influence of electro-magneto-hydrodynamics on the mass and heat transmission characteristics is the main aim of this study. The hybrid nanofluid is synthesized using water as a base fluid in the (Iron oxide) Fe 2 O 3 , single and multi-walled (SWCNTs/MWCNTs) carbon nanotubes (CNTs). The flow model has been arranged in form of PDEs, which are reduced into the system of dimensionless differential equations through a similarity approach. The differential equations are further treated with HAM to get analytic results. The impact of the Reynolds number, magnetic, electric and rotation parameters, on the drag force, mass flux and heat transmission rate has been scrutinized and discussed. The arithmetic consequences are carried out for Nusselt number, Sherwood number and drag force. The heat transmission has been considered to increase with the Reynolds number, magnetic constraint and electric parameter. The electric parameter improving the momentum boundary layer and drop the thermal boundary layer. The outcomes are compared with the existing literature and a closed agreement has found.
In this investigation, heat transportation together with irreversibility analysis for the flow of couple stress hybrid nanofluid past over a stretching surface is considered. The innovative characteristics and aims of this work are to note that the transportation heat couple stress model involves EMHD, viscous dissipation, Joule heating, and heat absorption, and omission. The hybrid nanofluid is prepared due to the suspension of the solid nanoparticles of the SWCNTs and MWCNTs in pure human blood. This mathematical model is an appropriate model for biological advantages including testing of human blood for drug deliveries to various parts of the human body. Particularly, the Prandtl number used for the blood is 21 and very large as compared to the other base fluids. Necessary modifications are used to translate the defining partial differential equations and boundary conditions into a layout that can be computed. To obtain mathematical approximations for the resulting scheme of nonlinear differential equations, the innovative homotopy analysis method (HAM) is used. The explanation for velocity, energy, and entropy are exposed and the flow against various influential factors ($$E,\;M,\;k,\;Q,\;S\;{\text{and}}\;Ec$$ E , M , k , Q , S and E c ) is discussed graphically. The numerical values are calculated and summarized for dimensionless $$C_{{fx}} \;{\text{and}}\;Nu_{x} .$$ C fx and N u x . In addition, the current study is compared for various values of $$\Pr$$ Pr to that published literature and an impressive agreement in terms of finding is reported. It has also been noticed that the $$M$$ M and $$E$$ E factors retard the hybrid nanofluid flow, while the temperature of fluid becomes upsurges by the rise in these factors. 11.95% enhancement in the heat transfer rate has been attained using the hybrid nanofluids.
