Question

Why do we feel more heat when we keep one hand above the candle flame than

keeping on the side of the candle flame?​

Answer 1

Answer:

Now, heat the water by placing the candle just below the crystal. Notice that towards the top, the air gets heated by convection. Therefore, the hand above the flame feels hot. On the sides, however, there is no convection and air does not feel as hot as at the top.

Explanation:

Answer 2

I'll take a shot here. Methods of heat transfer. Heat rises so when you hold your fingers above the flame convection transfers the energy to your digits. When you are on the side of the flame radiation is the transfer method. With a small flame radiation is not very powerful BUT as a fire grows radiation becomes a very strong effect. If memory serves every time the fire doubles the radiation transfer quadruples. In an active structure fire radiation is the main way things get ignited that seem to have no direct contact with the flames ( though radiational transfer does require line of sight between the source and the affected fuel, but I have rambled long enough :)

Hope this helped and wasn't too confusing.
