heat density
2.The Convection and radiation between smoke and trunk of bigger arbor, smaller arbor, bush, and leaves of bigger arbor, was calculated, their total quantity of heat and density of heat were compared respectively, and the in- fluences of velocity and ternperature of smoke flow, size of woods, reflux zone on heat transfer wer discussed as well.
