Abstract
The stagnation point flow over a heated stretching cylinder is mathematically modeled under the assumptions of phase flow approach. The interaction of impinging stagnation flow with the flow developed due to stretching surface of cylinder is thoroughly interpreted. To consider the underlying phase flow approach, water is used as the base fluid with multi-wall carbon nanoparticles. Exact analytical solutions are computed for this interesting problem and the results are evaluated graphically as well. A descriptive heat transport analysis with graphical interpretation of Nusselt number (Nu) is incorporated as well. Streamlines are included to analyze the flow visualization for the dominant impact of stretching developed flow or the dominance of impinging stagnation flow due to oncoming pressure. A more powerful or fully developed impinging stagnation flow is observed for the higher values of oncoming flow pressure parameter β when stretching cylinder has lower stretching velocity A. We can say that the stagnation flow is dominant over stretching flow if higher oncoming pressure flow values are taken. Most of the literature work provided on stagnation point flow covers the topic through numerical techniques, however in our study we aim to present some exact solution for the problem under consideration.
