Abstract
In this work, nanofluid's stagnation point flow is studied considering a stretchable cylinder that is oriented vertically with the perspective of application in irrigation systems and biotechnology. The study carried the modified Fourier's flux and buoyancy force. The prescribed surface temperature (PST) is utilized. The governing PDEs initially transformed into ODE. A numeric technique based on the Newton forward difference scheme is used to feature extraction of velocity, concentration, and temperature against the parameters having physical worth. The outcomes are studied through sketching the graphs of numeric data received. We perceived that the higher value of the unsteadiness parameter reduces the velocity, temperature, and concentration profile while the enhancing buoyancy boosted the velocity profile.
