Abstract
The second grade nanofluid flow with Cattaneo-Christov heat flux model by a stretching disk is examined in this paper. The nanofluid flow is characterized with Hall current, Brownian motion and thermophoresis influences. Entropy optimization with nonlinear thermal radiation, Joule heating and heat absorption/generation is also presented. The convergence of an analytical approach (HAM) is shown. Variation in the nanofluid flow profiles (velocities, thermal, concentration, total entropy, Bejan number) via influential parameters and number are also presented. Radial velocity, axial velocity and total entropy are enhanced with the Weissenberg number. Axial velocity, tangential velocity and Bejan number are heightened with the Hall parameter. The total entropy profile is enhanced with the Brinkman number, diffusion parameter, magnetic parameter and temperature difference. The Bejan number profile is heightened with the diffusion parameter and temperature difference. Arithmetical values of physical quantities are illustrated in Tables.

Summary
The enhancement of heat transfer utilizing nanofluids, in solar collectors, has been gaining much attention among researchers. The thermal and mass transmission in a nanofluid flow with chemical reaction and thermal radiation influences was presented by Sreedevi et al [4]. The MHD flow of Oldroyd-B nanofluid with a heat flux model was analytically proposed by Mustafa [16]. The unsteady flow of Williamson fluid with radiation and heat source/sink influences was examined by Khan and. The thermal transfer in an upper convected Maxwell fluid flow with C-C model was invested by Mustafa [23]. Aurangzeeb et al [30] investigated the mixed convection flow with chemical reaction, heat generation and the Hall current. The MHD viscoelastic flow of fluid with hall current and convective conditions was analyzed by Kumar and Chand [33].
