Description
Summary:This research delves into evaluating thermal radiative flux and energy in a micropolar nanofluid undergoing stagnation point flow. Its primary objective is to better understand heat transfer characteristics and energy distribution within the flow field. The study comprehensively analyses the nanofluid's thermal behavior, specifically exploring the influence of relevant factors on energy distribution. Through graphical representations of the results and in-depth discussions, valuable insights are gleaned regarding the thermal performance of micropolar nanofluids in stagnation point flows. The partial differential equations for the developed model altered into a system of nonlinear ordinary differential equations of dimensional free statements. These are numerically solved using the Runge–Kutta–Fehlberg integration schema and shooting technique. The obtained results are visually presented through graphs and extensively discussed. As observed, the velocity field decreases with various values of porosity and Prandtl terms and temperature distribution is raised by about 0.25%, correspondingly with increasing values of thermophoresis and radiation.
