The present work deals with the impact of hybrid nanoparticles (Au-Al2O3) on the blood flow pattern through a porous cylindrical artery with a bell-shaped stenosis in the presence of an external magnetic field, Joule heating, and viscous dissipation by considering two-dimensional pulsatile blood flow. The temperature-dependent viscosity model is utilized in this study. The blood flow is assumed to be unsteady, laminar, viscous, and incompressible. The mild stenotic presumption normalizes and reduces the bi-directional flow to uni-directional. The Crank-Nicolson scheme is applied to solve the continuity, momentum, and energy equations with appropriate initial and boundary conditions. Transport characteristics are visualized graphically for key dimensionless parameters such as Magnetic number ([Formula: see text]), Darcy number ( Da), Grashof number ( Gr), viscosity parameter ( β0), Reynolds number ( Re), Eckert Number ( Ec), Prandtl number ( Pr), different concentration of both the nanoparticles ( ϕ1, ϕ2), and pressure gradient parameter ( B1). The velocity contours for different emerging parameters have also been drawn to assess the overall behaviour of blood flow patterns. The non-dimensional velocity profile is enhanced with increment in values of Da, implying that the medium permeability provides less resistance to the flow. Increasing viscous dissipation ( Ec) and Joule heating ([Formula: see text]) parameter simultaneously raise the nanofluid temperature. Hybrid nanoparticles (Au-Al2O3/blood) effectively reduce hemodynamic variables such as wall shear stress and resistance (impedance). The present work finds applications in nano-mediated treatment of atherosclerosis and other diseases.

“…Therefore, it is urgent to find a better way to increase the flow stability in ALIP with less sacrifice in the pump efficiency. Chatterjee et al [27][28][29][30][31][32] simulated the pipe flow of nanofluid under different magnetic fields and variable thermal conductivities and studied the effects of different flow parameters on velocity distribution, wall shear stress, and flow function.…”

The strong coupling between fluid and electromagnetic field in the annular linear induction pump (ALIP) can gradually amplify small disturbance in the fluid field into large-scale vortices. The appearance of the vortices seriously affects the efficiency and reliability of the pump. An active flow control method based on the modification of the driving electromagnetic field is proposed to improve the flow stability. A simplified numerical model of the ALIP is established to simulate the three-dimensional flow in the annular flow channel, and the internal electromagnetic field is modified by using the modulated surface current. The influences of the active flow control method on the flow behavior, pressure pulsation, and energy conversion are, respectively, investigated based on the simulation results. The results show that the modulated surface current can accelerate the vortical evolution. The size and strength of the vortices are suppressed in the modified electromagnetic field. The pressure pulsation low frequency at the ALIP’s outlet is significantly reduced when the modulated surface current density reaches a certain level. The surges in the processes of energy conversion become more gentle within the control method, and the overall energy efficiency is slightly reduced even at the highest modulated surface current density.

Rotational buoyancy assumes a substantial role in a multitude of natural and engineering systems, with particular emphasis on astrophysical and geophysical scenarios. The primary objective of this study is to delve into the intricate dynamics of a rotational flow subjected to forces from rotational buoyancy, magnetic field, Hall effects, and infrared radiation in a Casson fluid medium adjacent to a thermal plate. The LT technique is harnessed to yield the closed‐form solutions for the dimensionless governing flow system. Through graphical analyzes, the physical implications of key contextual parameters are elucidated. Our findings demonstrate that Hall currents and rotational buoyancy forces jointly act to restrict primary fluid motion while amplifying secondary motion. An upswing in the Casson parameter leads to a marked reduction in the magnitude of the velocity components. Furthermore, intensified infrared radiation results in a more flattened thermal distribution. The primary directional shear stress attenuates, while an inverse bias is observed for the shear stress along the secondary direction, particularly with higher values of the Hall and rotation parameters. The insights gained from this study have practical implications for the design and operation of various systems involving rotational components, such as rotary machinery, automotive systems, and industrial automation, and contribute to weather forecasting and climate modelling.
