Unsteady squeezing carbon nanotubes based nano-liquid flow with Cattaneo–Christov heat flux and homogeneous–heterogeneous reactions

Abstract

The amazing features of carbon nanotubes (CNTs), such as lightweight, high thermal conductivity, good electrical conductivity, mechanical and chemical stability, and physiochemical compatibility, make them highly desirous materials for use in the electrochemical gadgets. Having such magnificent characteristics of carbon nanotubes in mind, our aim in this study is to examine the time-dependent squeezing nanofluid flow of water-based single- and multi-walled carbon nanotubes (SWNTs and MWNTs) in attendance of homogenous–heterogeneous (h–h) reactions between two parallel disks. The present study further comprises the impacts of magnetohydrodynamics (MHD) and Cattaneo–Christov (C–C) heat flux. Numerical solution of ordinary differential equations after engaging apposite transformations is computed. Concentration, temperature, velocity, local Nusselt number, and skin friction coefficient are addressed. Presented analysis reveals that skin friction and Nusselt number show opposite behavior for squeezing parameter Sq for both water-based SWNTs and MWNTs. Furthermore, the velocity field grows for mass transfer parameter. An outstanding consensus is achieved when our presented results are compared with an already studied problem in limiting case. Thus, dependable results are being presented.
