Numerical study of the effect of Tio۲ nanofluid on radiant heat transfer in lamp bulbs

In this paper, a two-dimensional axial numerical effect of increasing the radiant heat transfer coefficient of Tio۲ nanofluid in a lamp bubble under a constant heat flux placed around the bubble. This results in an increase in the heat transfer coefficient of the flow transfer to the environment. And the thickness of the displacement boundary layer decreases, so by increasing the volume percentage of nanofluid by ۱.۲%, this leads to an increase in radiant heat transfer coefficient. Therefore, with increasing temperature and heat flux, we see the optimization of radiant heat transfer coefficient of ۱۲% in the lamp bulb to the environment
