WebConvection. Convection is the mode of heat transfer which occurs mostly in liquids and gases.In this method, heat transfer takes place with the actual motion of matter from one place within the body to the other. Often when we boil water we have seen bubbles and currents develop in the water on careful observation. WebThe velocity of propagation of smoldering downward through vertical samples was studied. They were (1) circular rods of rolled paper, (2) circular incense sticks, (3) strips of cardboard, and (4) piles of cardboard tightly bound with thread. The velocity v perpendicular to the firefront was observed in a chamber of temperature Ta.
