Impact of gold nanoparticles along with Maxwell velocity and Smoluchowski temperature slip boundary conditions on fluid flow: Sutterby model

Communication is structured to develop a novel three dimensional mathematical model regarding rotating Sutterby fluid flow subjected to a slippery expandable sheet. The heat transfer analysis has been carried out with the inclusion of effects like gold nanoparticles and thermal radiation. The mass transfer regarding the concentration of the fluid has been analysed with the utilization of the activation energy effect. Maxwell velocity and Smoluchowksi temperature slip boundary conditions have been employed. The mathematically modelled partial differential equations (PDEs) regarding momentum, energy, and concentration step down into ordinary differential equations (ODEs) with the utilization of suitable transformation. Matlab built-in bvp4c numerical scheme has been used to handle dimensionless ODEs. The physical quantities like surface drag coefficient, heat transfer as well as mass transfer in the case of variation in various sundry parameters are numerically computed and displayed in the form of tables and figures. The temperature field amplifies by the virtue of augmentation in gold nanoparticles volume fraction and an increment in activation energy booms the mass fraction field. It is observed that the presence of the thermal radiation parameter enhances the heat transfer rate 17.2% and mass transfer booms 62.1% in the case reaction rate constant.
