**Figure 2** describes the influence of Eckert number for platelet shape nanoparticle. By varying the value of Eckert, it can be seen that the temperature is increasing. Physically, it can be seen that the Eckert number enhances the thermal conductivity of the fluid. **Figure 3** shows that the increase in the value of the Prandtl number results

in deceleration in temperature because of the reduction in thermal diffusivity. As the unsteadiness parameter increases, the temperature gradually decreases, as shown in **Figure 4**. Physically the value of the unsteadiness parameter is grown up, and the thickness of the thermal boundary layer decreases, which results in a decline in the temperature profile.
