Summary

The blood flow analysis inside a narrow arterial segment is already being studied by recent researchers due to a wide range of applications in engineering sciences. The narrow section inside an artery is formed due to the integration of plaque on the walls of arterial segment. This narrowing of the channel results in a declined blood flow profile and the supply of oxygen, nutrients, and blood cells is restricted to the heart muscles which causes chest pain or shortness of breathing, etc. The study of blood flow inside such affected arterial sections provides the necessary data on the behavior of flow, locating a plaque integration or necessary information needed for bypass purposes. We aim to publish a special collection on this topic that accumulates the blood flow analysis inside various kinds of stenosis formations, shapes, different channels, etc. How various non-Newtonian models can be considered for this analysis and why a specific model is better to choose for this study. How the analysis is affected under influence of nano-materials etc. The work aims to include exact analytical as well as numerical solutions with simulation work. The relevant research area of the journal includes the study of fluids and computational mechanics or computational biology.

    Unsteady MHD Casson Nanofluid Flow Past an Exponentially Accelerated Vertical Plate: An Analytical Strategy

    T. Aghalya, R. Tamizharasi
    CMES-Computer Modeling in Engineering & Sciences, Vol.140, No.1, pp. 431-460, 2024, DOI:10.32604/cmes.2024.046635
    (This article belongs to the Special Issue: Numerical Modeling and Simulations on Non-Newtonian Flow Problems)
    Abstract In this study, the characteristics of heat transfer on an unsteady magnetohydrodynamic (MHD) Casson nanofluid over an exponentially accelerated vertical porous plate with rotating effects were investigated. The flow was driven by the combined effects of the magnetic field, heat radiation, heat source/sink and chemical reaction. Copper oxide () and titanium oxide () are acknowledged as nanoparticle materials. The nondimensional governing equations were subjected to the Laplace transformation technique to derive closed-form solutions. Graphical representations are provided to analyze how changes in physical parameters, such as the magnetic field, heat radiation, heat source/sink and chemical… More >

    Natural Convection and Irreversibility of Nanofluid Due to Inclined Magnetohydrodynamics (MHD) Filled in a Cavity with Y-Shape Heated Fin: FEM Computational Configuration

    Afraz Hussain Majeed, Rashid Mahmood, Sayed M. Eldin, Imran Saddique, S. Saleem, Muhammad Jawad
    CMES-Computer Modeling in Engineering & Sciences, Vol.139, No.2, pp. 1505-1519, 2024, DOI:10.32604/cmes.2023.030255
    (This article belongs to the Special Issue: Numerical Modeling and Simulations on Non-Newtonian Flow Problems)
    Abstract This study explains the entropy process of natural convective heating in the nanofluid-saturated cavity in a heated fin and magnetic field. The temperature is constant on the Y-shaped fin, insulating the top wall while the remaining walls remain cold. All walls are subject to impermeability and non-slip conditions. The mathematical modeling of the problem is demonstrated by the continuity, momentum, and energy equations incorporating the inclined magnetic field. For elucidating the flow characteristics Finite Element Method (FEM) is implemented using stable FE pair. A hybrid fine mesh is used for discretizing the domain. Velocity and More >

    Radiative Blood-Based Hybrid Copper-Graphene Nanoliquid Flows along a Source-Heated Leaning Cylinder

    Siti Nur Ainsyah Ghani, Noor Fadiya Mohd Noor
    CMES-Computer Modeling in Engineering & Sciences, Vol.139, No.1, pp. 1017-1037, 2024, DOI:10.32604/cmes.2023.031372
    (This article belongs to the Special Issue: Numerical Modeling and Simulations on Non-Newtonian Flow Problems)
    Abstract Variant graphene, graphene oxides (GO), and graphene nanoplatelets (GNP) dispersed in blood-based copper (Cu) nanoliquids over a leaning permeable cylinder are the focus of this study. These forms of graphene are highly beneficial in the biological and medical fields for cancer therapy, anti-infection measures, and drug delivery. The non-Newtonian Sutterby (blood-based) hybrid nanoliquid flows are generalized within the context of the Tiwari-Das model to simulate the effects of radiation and heating sources. The governing partial differential equations are reformulated into a nonlinear set of ordinary differential equations using similar transformational expressions. These equations are then… More >

    CMES-Computer Modeling in Engineering & Sciences, Vol.138, No.2, pp. 1485-1499, 2024, DOI:10.32604/cmes.2023.029351
    (This article belongs to the Special Issue: Numerical Modeling and Simulations on Non-Newtonian Flow Problems)
    Abstract This work investigates an oblique stagnation point flow of hybrid nanofluid over a rigid surface with power law fluid as lubricated layers. Copper (Cu) and Silver (Ag) solid particles are used as hybrid particles acting in water H2O as a base fluid. The mathematical formulation of flow configuration is presented in terms of differential system that is nonlinear in nature. The thermal aspects of the flow field are also investigated by assuming the surface is a heated surface with a constant temperature T. Numerical solutions to the governing mathematical model are calculated by the RK45 algorithm. More >

    Abstract The application of mathematical modeling to biological fluids is of utmost importance, as it has diverse applications in medicine. The peristaltic mechanism plays a crucial role in understanding numerous biological flows. In this paper, we present a theoretical investigation of the double diffusion convection in the peristaltic transport of a Prandtl nanofluid through an asymmetric tapered channel under the combined action of thermal radiation and an induced magnetic field. The equations for the current flow scenario are developed, incorporating relevant assumptions, and considering the effect of viscous dissipation. The impact of thermal radiation and double… More >
