Heat and mass transfer in stagnation point flow of cross nanofluid over a permeable extending/contracting surface: A stability analysis

This work aims at examining the thermophoresis and Brownian motion characteristics on stagnation point flow of Cross nanofluid over a permeable stretching /contracting surface. Flow equations are modelled by means Buongiorno model. The transformed non-linear fluid transport solved numerically through Runge-Kutta Fehlberg (RKF) approach. temporal stability test is executed to reveal behaviour dual solution that arises for various initial guesses. To validate present model, first second solutions compared with earlier published works which found good agreement. fluctuations velocity, heat mass transfer distributions scrutinized graphs active parameters such as Wessienburg number, motion, Eckert thermophoresis. results exposed declines rate solution. velocity amplifies rising Weissenberg number. By impact has higher magnitude than For solution, cross rises when increasing suction/injection parameter.
