Entropy generation investigation of MHD Ag- and Au-H2O nanofluid above an exponential porous stretchable surface with thermal radiation and stagnation point flow

The current study presents an entropy generation investigation of magnetohydrodynamic Ag- and Au-H2O nanofluid flows induced by an exponential stretchable sheet implanted in porous media accompanying suction/injection and heat radiation impact. Moreover, the stagnation point flow and silver and gold nanoparticles are considered. The consequences of ohmic heating and thermal radiation are also included as part of the heat transport examination. A physical process is transformed into a set of mathematical expressions using mathematical concepts, which can then be further simplified by using the necessary variables. Considering numerous physiological factors of interest, exact solutions for velocity and temperature profiles are calculated. Graphs and numerical tables are utilized to examine how different physical entities affect the distribution of velocity, temperature, and entropy. It is noted that enhancing the values of omega reduces entropy inception. It is observed that the entropy inception field gains due to an increment in Ec(rt) .
