Summary: This article examines the magneto-bioconvective properties of nanofluid flow through a rotating cone using the Cattaneo-Christov heat flux model. The effects of cross diffusion, porous medium, Stefan blowing, and Navier slip are analyzed, and the governing equations are transformed into a system of self-similar ordinary differential equations. A parametric study is conducted to investigate the impact of various parameters on different fields, such as motile microorganisms density, nanoparticle concentration, and temperature. The results show that temperature decreases with increasing thermal relaxation parameter gamma, and an increase in magnetic parameter M leads to a decrease in energy field.

Summary: This article investigates the MHD Jeffrey fluid flow over a stretching cylinder with convection. The Cattaneo-Christov heat flux model is used instead of the Fourier law of heat conduction to derive an energy equation. The mathematical model leads to a system of nonlinear PDEs in cylindrical coordinates, which are transformed into ordinary differential equations using similarity transformations. The numerical solutions are obtained using shooting and BVP4C methods, and the results are validated. The effects of different parameters on velocity, temperature, and concentration are analyzed through graphs, and the skin-friction coefficient, local Nusselt and Schmidt numbers are discussed and tabulated. The novelty of this work lies in the study of Cattaneo-Christov MHD heat flux for Jeffrey fluid flow with convective conditions.

Summary: The impact of thermal stratification and thermally radiative flow of carbon nanotubes on a Riga plate with injection/suction and heat generation/consumption is investigated. The two varieties of base fluids, like, water and glycerin with single-wall nanotubes and multi-wall carbon nanotubes, are incorporated in this investigation. The consequences of the physical parameters on fluid velocity, fluid temperature, skin friction coefficients and local Nusselt number are explained through tables, graphs and charts. It is detected that the fluid velocity in both directions diminishes when raising the suction/injection and velocity slip parameters. The fluid temperature downturns when enhancing the suction/injection and stratification parameters. The surface shear stress suppresses when increasing the Forchheimer number. The radiation parameter leads to strengthening the heat transfer gradient.

Summary: The investigation analyzed the flow and heat transfer behavior of a non Newtonian fluid subject to an externally inclined magnetic field. The study revealed that the increase in magnetic field strength has an opposite effect on fluid velocity and temperature, while factors such as thermal relaxation time and curvature parameter play a role in controlling the rate of heat transportation. Additionally, the angle of inclination of the magnetic field affects the fluid flow in a reverse manner.

Summary: This study discusses the influence of non-Fourier heat flux on the 2D Darcy-Forchheimer flow of the modified Eyring-Powell model. The thermal conductivity of the model depends on temperature and porosity variables, and the effects of Cattaneo-Christov heat-mass flux are also considered. The resulting ordinary differential equations (ODEs) are solved numerically, and the graphical results show the behavior of various physical parameters. The findings indicate that the temperature gradient decreases with increasing Prandtl number, while the concentration profile decreases for higher Lewis numbers.

Summary: This research aims to study the behavior of fluid flow and heat transfer characteristics of water-based graphene oxide nanoparticles in heat transfer procedures with irregular heat source/sink. The acquired equations are transformed and solved numerically to obtain velocity profiles and temperature distributions of the nanoparticles. The results show that the velocity decelerates and the temperature increases with higher nanoparticle volume fraction under the influence of thermal radiation. The profiles of temperature are also affected by the internal heat source/sink parameter.

Summary: In this paper, the modified exp(-psi(theta))-function method is used to explore the solitary wave solutions for microtubules (MTs). By treating the problem as a nonlinear model partial differential equation, specific solutions to the nonlinear evolution equation (NLEE) are found, covering important parameters in biophysics and nanobiosciences. In addition to soliton-like pulse solutions, rational, trigonometric, hyperbolic, and exponential function characteristic solutions are also discovered. The validity and superiority of the proposed method are demonstrated through comparisons with other methods. Mathematica 10 software is then used to generate visual plots of the observed findings, validating the suggested technique and parameter values.

Summary: This study focuses on understanding the mechanisms and kinetics of homogeneous and heterogeneous reactions in ternary-hybrid nanofluids. The non-linear partial differential equations are transformed into ordinary differential equations using local similarity transformations and numerically solved using MATLAB. The Tiwari-Das model is used to study the flow-thermal behavior of the nanofluid, and thermal conductivity formulations are incorporated based on experimental works. The investigation shows that the strength of homogeneous and heterogeneous reactions has opposite effects on the concentration fields.

Summary: This study investigates the dynamics of waves in the conformable fractional (2+1)-dimensional Nizhnik-Novikov-Veselov (NNV) equations, which are the isotropic Lax integrable extension of the (1+1)-dimensional Korteweg-de Vries equations. Fractional differential models (FDMs) are introduced to describe more complex behavior and encompass all properties of the integer order model. The Hirota bilinear method (HBM) is successfully employed to obtain soliton solutions of the fractional nonlinear partial differential equations. Results show various solutions including lump-periodic, breather-type and two wave solutions, and numerical visualizations demonstrate the effects of fractionality and parameters. Experts in engineering models are expected to benefit from this research, as it presents an effective, quick, easy, and flexible algorithm for different systems.

Summary: This article uses COMSOL-Multiphysics to study laminar coupled mixed convection heat transfer in a horizontal channel-cavity architecture. The effect of heat source location on isotherms, velocity distribution, pressure, temperature, Nusselt numbers, and air density is investigated. The results show that the highest heat transfer occurs when the heat source is near the contact surface between the channel and the cavity. Changing the position of the heated source does not affect the velocity distribution or pressure distribution. Air density profiles differ around y = 0.035 m, with the third case having a higher density than the second case, which in turn has a higher density than the first case. The contact surface (y = 0) has the highest Nusselt number and exhibits the highest heat transfer.

The hybrid efficiency of GA-SQPS is used to optimize the error function for the disease model, resulting in good measures of absolute error. Statistical measures are also performed to assess the constancy, reliability, and effectiveness of ANN-GA-SQPS using different indices in 50 independent executions and 30 variables.

Summary: This research focuses on the significance of thermophoretic particle deposition in a nanolubricant flow in a stretchable/shrinkable convergent/divergent channel with the presence of a magnetic field and nonlinear heat radiation. The results show that stretching/shrinking the walls significantly affects the flow and heat properties. Stretching the channel increases the velocity profiles, while shrinking leads to backflow regions. In terms of temperature, stretching generates more heat, while shrinking reduces the thermal layer and achieves cooling.
