This paper analyzes the axisymmetric squeezing current phenomena of Cu‐water and Cu‐kerosene for two dimensional nanofluid between two parallel plates. The effects of thermal radiation with velocity slip are also enhancing the subject as well. The similarity approach has been adopted to obtain the ordinary differential equations from partial differential equations. The solution of these complex coupled nonlinear equations is obtained analytically using the variation parameter method. For the corroboration of the current result, we have matched with prior results in particular cases and concluded that both the results coincide with each other. Computations are obtained for velocity and temperature profiles for different pertinent parameters along with skin friction and Nusselt number and presented via graphs and tables.
Present study analyses the axisymmetric flows of copper-and silver-water nanofluids between two rotating disks in the presence of Hartmann number, porous medium, and drag coefficient. Effect of thermal radiation enriches the study as well. In addition to that, the coupling parameter and the Eckert number appear because of the inclusion of viscous dissipation in energy equation. The well-posed transformations are used to transform the governing equation into ordinary and semianalytical procedure, that is, Adomain Decomposition method is used to solved these coupled ODEs. The surface and contour plots for the velocity profiles of both Cu-and Ag-water nanofluids for the effect of physical parameters such as solid volume fraction, drag coefficient, and Reynolds number are obtained and presented in graphs. Also, the behavior of other pertinent parameters characterizes the flow phenomena on the nanofluid velocity and temperature are presented through graphs. The numerical computation of skin friction and Nusselt number are obtained and presented through tables. For the validity, the present results show a good agreement with earlier studies. The major findings of this study are as follows: an increase in solid volume fraction, a resistive force like drag opposes the velocity of the nanofluid, whereas Eckert number enhances the fluid temperature significantly.
