Analysis of thermal radiation, Joule heating, and viscous dissipation effects on blood‐gold couple stress nanofluid flow driven by electroosmosis

Abstract

Gold nanoparticles associated with DNA, RNA, proteins, oligonucleotides, and peptides are useful in therapies and drug delivery. The present article mainatins that gold nanoparticles play a tremendous role in remedying cancer and fatal diseases. A mathematical model is proposed for the two-dimensional motion of the couple stress nanofluid consisting of gold nanoparticles under the application of peristaltic propulsion and electroosmosis mechanisms in an asymmetric microchannel. The effects of radiation with slip boundary have been employed. The governing equations are simplified under the assumptions of low Reynolds number and long wavelength and the Poisson-Boltzmann equation is solved under Debye-Hückel linearization. Analytical solutions for the velocity of fluid motion, nanoparticle temperature, stream function, pressure gradient, are evaluated and analyzed graphically under the effects of various physical parameters. It is notable from the analysis that raising the Brinkman number boosts the nanoparticle temperature and heat transfer coefficient which validate the physical model and analysis. Moreover, it is noticed that sphere-shaped gold

Heat transfer and electroosmosis driven MHD peristaltic pumping in a microchannel with multiple slips and fluid properties

“…Hematocrit level and electric field variation affected the capillary filling process in microchannels, as stated by Chakraborty. 14 Recently, numerous researchers have studied the impact of electroosmosis modulated peristaltic flow in various geometries [15][16][17][18][19][20][21][22][23][24][25] and discussed the effects of the zeta potential, EDL thickness, and external electric field effects in both directions (in direction of fluid flow as well in the opposite direction of fluids flow) on the physiological transport phenomena and also reported that electric field could be applicable to control the physiological transport and maintain the electrolyte level of the physiological systems.…”

Analysis of dissipative non‐Newtonian magnetic polymer flow from a curved stretching surface with slip and radiative effects

“…Ferdows et al 37 studied the impact of radiative flux on hydromagnetic flow from a curved stretching sheet, using MATLAB bvp4c quadrature, noting that the fluid velocity and temperature increase with curvature parameter, whereas higher magnetic parameter reduces velocity. Sridhar et al 38 have reported the combined effects of Joule heating and radiation on non-Newtonian fluid flow. Further analyses reporting on the dual effects of thermal radiation and Ohmic heating on stretching sheet flows include Sajid et al 39 (on ferrofluids), Shamshuddin et al 40,41 (on micropolar magnetic polymers and pseudoplastic magnetic polymers), and Prakash et al 42 (who used a tangent hyperbolic rheological model for biaxial electro-MHD stretching flow).…”
