  • Numerical investigation of Williamson fluid in presence of chemical reaction towards a parabolic surface
    P. R. Sobhana Babu, P. Jayalakshmi, D. V. N. S. R. Murthy, Ch. Srinivasulu, W. Sridhar
    International Journal of Modelling and Simulation, 2024
    Our focus here is on examining the behavior of a boundary layer that regulates the movement of a non-Newtonian fluid undergoing a chemical reaction on a radiative paraboloid surface. This includes studying the fluid’s movement, temperature, and mass transfer. The fluid being studied pertains to the Williamson fluid model, which is described as a type of extended Newtonian fluid. We have considered the effects of Joule heating and dissipation through viscous phenomena based on the rules of heat and mass movement. The equations in the mathematical structure of partial differential equations (PDEs) governing the fluid continue to flow model in the problem. A subsequent evolution of these equations into ODEs by incorporating similarity variables. The velocity field’s schematic behavior is attributable to the magnetic parameter, thickness parameter, and the Weissenberg number, which exhibit velocity profile decline. In this research, both thermal radiation and Eckert number are highlighted, and it is concluded that both of these variables substantially raise the temperature field. We continue to track the concentration-reducing chemical reaction characteristic that remains tracked along with concentration transfer. Furthermore, the study includes a comprehensive presentation of comparative analyses with previously published scholarly works.
  • Heat Transfer Analysis of Sisko Fluid Flow over a Stretching Sheet in a Conducting Field with Newtonian Heating and Constant Heat Flux

    Energies, 2023
    The present study investigates the steady three-dimensional flow of a Sisko fluid over a bidirectional stretching sheet under the influence of Lorentz force. Heat transfer effects have been carried out for constant heat flux and Newtonian heating systems. The transformed governing equations of the flow model are solved by using the spectral relaxation method (SRM), taking into account similarity transformations. The effects of controlling parameters on flow and derived quantities have been presented in the form of graphs and tables. Numerical benchmarks are used to characterise the effects of skin friction and heat transfer rates. It is noticed that in the case of Newtonian heating, the rate of heat transfer is higher than that in the constant heat flux case. As the stretching parameter increases, the fluid temperature decreases in both Newtonian heating and constant heat flux. It was discovered that successive over (under) relaxation (SOR) approaches will considerably boost the convergence speed and stability of the SRM system. The current findings strongly agree with earlier studies in the case of Newtonian fluid when the magnetic field is absent.

    Case Studies in Thermal Engineering, 2023
    Owing to improved thermal efficiencies of hybrid nanomaterials, various applications of such tiny particles are claimed in enhancing thermal impact in heat transfer phenomenon, improving the efficiencies of solar collectors, thermal management systems and different industrial processes. Following to such motivations in mind, this research communicates the thermal impact of hybrid nanofluid with utilization of different nanoparticles due to porous infinite plate. The characterization of hybrid nanoparticles is observed with interaction of copper (Cu), aluminium oxide (Al2O3), titanium oxide (TiO2) with water base fluid The phenomenon is supported with thermal radiation phenomenon. The porous medium with uniform permeability is considered within flow regime. The onset of chemical reaction is attributed in concentration equations. The closed form solution is obtained via analytical procedure. The thermal assessment of nanoparticles in flow regime with effect of different parameters is considered. The comparative thermal observations are reported for pure nanofluid and with different nanoparticles.
  • The axisymmetric flow of an MHD Powell–Eyring fluid with viscous dissipation and Newtonian heating condition: Keller-box method
    P. Jayalakshmi, K. Gangadhar, M. Obulesu, P. Madhu Mohan Reddy
    Heat Transfer, 2023
    Abstract A special investigation on the heat transfer by applying viscous dissipation and considering the Newtonian heating condition in magnetohydrodynamic Powell–Eyring fluid has been attempted. It is regarded as the flow in an axisymmetrical direction over a radially stretching surface. The converted governing system of equations is solved to obtain a closed‐form solution using the Keller‐box technique. The skin‐friction coefficient's influence fully developed local Nusselt number is then presented graphically, and temperature profiles are sorted out for the pertinent parameters. The fluid overshoot towards the plate surface with rising magnetic field strength, hence, both the fluid velocity and the hydrodynamic border line layer thickness will fall, though, the skin‐friction coefficient will increase. Various relevant results of the energy indulgence have been discussed from heating and in view of viscous dissipation phenomena. The decision with minimal cases from previous studies in the literature received confirmation of the findings.

    International Journal of Design and Nature and Ecodynamics, 2022
    In this article, an analysis of magnetohydrodynamic fluid flow in addition to heat transfer involving a nanofluid flowing through a stretched cylinder has been performed in the being there of Newtonian heating. In the heating and cooling processing sectors, Newtonian heating is particularly essential. Utilizing similarity transformations, in the absence of appropriate boundary conditions, ordinary differential equations are a collection of equations that are used to solve problems (ODE) corresponds to the governing partial differential equations (PDE), The Runge-Kutta-Gill technique and the shooting strategy are then used to numerically solve the problems. Water has been used as the foundation fluid for a variety of nanoparticles, including Copper (Cu), Silver (Ag), Alumina (Al2O3), and Titanium Oxide (TiO2). The present results used for the surface Shear stress and the local Nusselt number are in very good agreement with those previously published. Advanced skin friction coefficients and heat transfer rates were found to be increased with M and Re valued higher. In addition, copper (for a small amount of magnetic parameter) and alumina (for a large amount of magnetic parameter) the optimum cooling materials for this problem have also been found.
  • Dual solutions for MHD Casson fluid over a shrinking sheet with Newtonian heating
    K. Gangadhar, T. Kannan, P. Jayalakshmi, G. Sakthivel
    International Journal of Ambient Energy, 2021
    This paper reports the dual solutions in the MHD flow of a Casson fluid over a porous shrinking surface. In this study, viscous dissipation and Newtonian heating boundary condition effects are investigated. The governing partial differential equations are transformed into dimensionless form by the similarity transformation and then numerically solved by the Runge–Kutta–Gill procedure together with the shooting method. The non-dimensional velocity, temperature are displayed graphically for different controlling parameters. Dual similarity solutions are obtained for dimensionless velocity and temperature profiles. It is observed that the thermal boundary layer thickness increases as the Newtonian heating parameter increases in the presence of magnetic field.
