Abstract
An analysis of heat and mass transfer that occur in copper–alumina/water nanofluids flow past a stretching surface is presented. This flow is influenced by cross-diffusion effects and viscous dissipation. After the application of appropriate similarity transformations on governing equations, the resultant system is solved by Spectral Relaxation Method. The variations of velocity, temperature, concentration and results for skin friction coefficient, local Nusselt number and local Sherwood number for Cu–Al2O3/ water nanofluids with different flow parameter values are manifested through graphs and tables. Temperature enhancement is observed due to an increase in the Dufour number. Concentration distribution increased for higher Soret numbers and decreased for higher Schmidt numbers. Also, numerical values are calculated for effective local Nusselt number as well as local Sherwood number due to the influences of Dufour and Soret and are tabulated. The validation of the present investigation is ensured by comparing it with already published studies.
