Numerical analysis of heat source/sink on peristalsis of MHD carbon-water nanofluid in symmetric channel with permeable space

Abstract

Nanoparticles of carbon has auspicious uses in a biomedical procedures like energy storage, catalyst supports, biomedical, in drug targeting system, in cancer treatment, in biological therapy, in blood diagnostic and coagulation systems. Motivated from these processes, peristalsis features have been accounted to study the mixed convection of the nanofluid, that is, Carbon-water in a vertical type channel with symmetric walls. Heat transport of magneto-hydro nanoliquid flow inside porous media is scrutinized. Single wall and multiwall Carbon nanotubes with water based nanoparticles are considered. Viscosity is prescribed as variable. The channel boundaries satisfy wall compliant and slip condition. Heat generation or absorption term is present. Assumptions of small Reynolds number along with long wave length are implemented for mathematical modeling. Transformed form of flow equations are evaluated by using numerical scheme. Through different parameters, graphical behaviors of temperature and velocity are displayed and elaborated. Moreover heat transfer rate is computed. Results revealed that for larger [Formula: see text], velocity is minimum at upper region and it grows in the lower region. The larger variation in [Formula: see text] leads deceleration in the velocity in lower portion and an enhancement is observed in velocity in upper portion. Further, it is seen that the heat transfer rate is larger for the MWCNT nanoparticles case as compared to the case of SWCNT nanoparticles.

Unsteady natural convection flow of blood Casson nanofluid (Au) in a cylinder: nano-cryosurgery applications

“…Later, researchers extend their study in the cylindrical domain with various fluid models since it is close to the actual applications such as Jiang et al 61 and Shah et al 62 studied Oldroyd-B fluid meanwhile Padma et al 63 , 64 studied Jeffrey fluid model as blood. Besides that, researchers also numerically investigated the slip velocity effect of the nanofluid model in different geometries and fluid models such as nanofluid flow on the plate with Casson nanofluid model 65 – 68 and Newtonian nanofluid model 69 , nanofluid flow in a channel with Rabinowitsch nanofluid model 70 , Newtonian carbon nanotubes model 71 and Casson nanofluid model 72 , 73 , nanofluid flow in cylindrical domain with Casson nanofluid model 74 – 76 . None of them solved analytically for Casson nanofluid with slip velocity effect in the cylindrical domain.…”

Investigation of variable thermal relaxation time in non-Fourier heat transfer flow with nonlinear thermal stratification

“…Reddy et al 24 disclosed the features of electric and magnetic fields in nanofluid flow via porous medium. Sheriff et al 25 explored the porosity features in hydromagnetic peristaltic transportation of nanofluid through symmetric channel considering heat source/ sink. Khan et al 26 described the stratification analysis in squeezed fluid flow through porous medium under convective features.…”
