Computational treatment of statistical declaration probable error for flow of nanomaterials with irreversibility

Abstract

The current investigation deals with entropy analysis for radiative flow of nanomaterials between two heated rotating disks. Titanium ([Formula: see text] and [Formula: see text]) and Graphene oxides are taken as nanoparticles. Water ([Formula: see text]) is used as a conventional base liquid. Dissipation and radiation effects are incorporated in energy equation. Rotating disks have different angular velocities. Both disks have different stretching rates. Attention is focused for statistical declaration and probable error. Physical feature of entropy analysis is studied through thermodynamics second law. Nonlinear partial system (PDEs) is reduced to ordinary one (ODEs). Homotopy analysis technique (HAM) is used for convergent series solution. Features of sundry variables on entropy optimization, temperature, Bejan number, and velocity are discussed for both nanoparticles ([Formula: see text] and [Formula: see text]). Computational outcomes for velocity gradient and Nusselt number are addressed through tabulated values. For larger Reynold number the radial and axial velocities are decreased. Temperature is augmented for against higher Eckert number and radiation parameter. Bejan number and entropy rate are augmented versus radiation parameter. Bejan number and Entropy rate have opposite trend via Reynold number. Statistical declaration and probable error are deliberated via Tables.

Comparative simulation of nonlinear radiative nano casson and maxwell fluids with periodic magnetic force and sensitivity analysis

“…Furthermore, to complete their work, an explicit finite difference method was used where temperature, concentration, and velocity profile were investigated graphically. Between two heated rotating disks Hayat et al [ 4 ] investigated entropy for a radiative water based nanofluid. With the presence of two different nanoparticles into base fluid, Wang et al [ 5 ] presented a numerical analysis on a microchannel porous media.…”

“…Also, Esfe et al [ 12 ] expolred the natural convective heat transfer behaviour on a U-shaped cavity. Hayat et al [ 13 ] studied on entropy generation for the radiative flow of nanomaterials across two heated spinning disks. Sayed et al [ 14 ] employed Legendre-Galerkin method to examine the nanofluid flow across an upward cone and how heat transfers under the impacts of thermal radiation and heat creation.…”

Numerical Simulation and Sensitivity Analysis Using RSM on Natural Convective Heat Exchanger Containing Hybrid Nanofluids

“…Nanofluid has numerous practical applications in industry and health science, such as in semiconductors, solar engineering, thermal storage systems, microelectronics, electronic devices, computer processors, nuclear reactor cooling, biomedical engineering, cancer therapy, etc. To heighten the thermal performance of base fluid, at different times, already there have been extensive studies about Cu, CuO, Ag, Al 2 O 3 , Fe 3 O 4 , and TiO 2 suspension into a base fluid in numerous fluid domains [8][9][10][11][12][13][14][15][16]. To explain the significance of nanofluid, Rostami et al [17] described natural convective heat transfer models with and without the existence of nanoparticles into the base fluids.…”
