Abstract
The primary objective of the present work is to examine the axisymmetric flow and heat transfer over an unsteady radially stretching surface for different shapes of silver (Ag) nanoparticles. Due to their remarkable electrical conductivity and chemical stability for a variety of applications, silver nanoparticles are attracting attention. So, we consider five different shapes of silver nanoparticles. By using suitable transformation energy and momentum equations are transformed into nonlinear ordinary differential equations. The dimensionless equations are solved by BVP4C technique to get numerical results for the modeled problem. For velocity, temperature, skin friction coefficient, and Nusselt number, numerical values are obtained using and are also graphically displayed. Comprehensive discussion is given on the effects of many factors, including solid volume fraction, Prandtl number, unsteadiness parameter, magnetic parameter, slip parameter, and Eckert number. For both velocity and temperature Platelet shapes nanoparticles shows maximum flow and heat transfer. Sphere shape nanoparticles possess the highest skin friction coefficients values and lowest value of Nusselt number.
