EFFECTS OF CHEMICAL REACTION AND SLIP IN THE BOUNDARY LAYER OF MHD NANOFLUID FLOW THROUGH A SEMI-INFINITE STRETCHING SHEET WITH THERMOPHORESIS AND BROWNIAN MOTION: THE LIE GROUP ANALYSIS

摘要

The present work aims to study the heat and mass transfer of a steady two-dimensional incompressible Cu–water nanofluid flow over a semi-infinite stretching sheet with slip, chemical reaction, thermophoresis, and Brownian motion effects. The obtained governing equations are transformed using the Lie group and similarity transformations and finally solving them by the 4th–5th-order Runge–Kutta–Fehlberg method with a shooting technique. The results show that the heat transfer rate slows down as both the slip parameter and chemical reaction rate parameter increase, while the rate of mass transfer shows a reverse effect of the slip parameter and chemical reaction rate parameter as that for the heat transfer rate.
