For both nanosphere (a) and nanorod (b), there is a plume like high velocity zone forming above the nanoparticles as the fluid elements gain enough momentum only upon moving some distance. The difference in velocity magnitude between the nanosphere (a) and nanorod (b) is again due to the difference in the laser intensity. Figure (a) shows the 3D velocity vectors representing the rise of fluid around a nanorod placed horizontally close to the bottom wall (180 nm from the bottom) in a hemispherical enclosure. The comparison between slip and no-slip boundary condition is shown in Figure (c). In Figure (d), the distance of the nanorod from the bottom is increased from 180 nm in (c) to 360 nm. Apparently, doubling the distance also doubles the velocity magnitude. Thus, the effect of the proximity of the nanoparticle from the wall is significant on the flow strength. As shown in Figure (e), instead of a constant temperature boundary condition on the bottom wall, if we have an adiabatic bottom wall, the system retains more heat and the temperature of the nanoparticle and the velocity magnitude is much higher. When bottom wall to the nanorod distance is 180 nm, the temperature of the horizontally oriented nanorod is 80.1 which is lower than that for a nano-rod oriented vertically (83.4 o C) since more surface area is facing the bottom wall in the horizontal orientation. On the other hand, the horizontally oriented nanorod is shifted to a distance of 360 nm from 180 nm, the steady state temperature increases from 80.1 to 83.
