Thermal aspect of boron nitride nanotubes (BNNT) and multiwall carbon nanotubes (MWCNT) with distinct physical features: Keller Box simulations

Abstract

The research on hybrid nanofluid has been focused by researchers widely in the current decade. Being the combination of two distinct nanoparticles, the researchers have predicted the thermal efficiencies of hybrid nanofluid model in view of distinct nanoparticles. However, the no attention is devoted by researchers towards the thermal mechanism of hybrid nanofluid with boron nitride nanotubes (BNNTs) and multiwall carbon nanotubes (MWCNTs) with distinct impressive characteristics. This communication aims explore the thermal flow of BNNTs and MWCNTs confining the axisymmetric rotational stagnation point flow executing by a bi-axial stretching surface. The numerical computations are performed the implementation of Keller Box numerical technique. The results verification is done via making the comparative analysis. The thermal aspect of hybrid nanofluid model is entertained. The physical inspection of the formulated problem with flow parameters is done in terms of distinct graphs. It is observed that increase in the solid volume fraction of BNNTs enhanced the velocity profile. The temperature profile declined with stretching parameter for MWCNTs and hybrid nanofluid. The Nusselt number increases for thermal Biot number and increasing change is more progressive for hybrid nanomaterials as compared to MWCNTs.
