Experimental study on + shaped high conductivity constructal channels based on entransy theory
Acta Physica Sinica, 2016 Based on constructal theory and entransy theory, an experimental study on + shaped high conductivity channels in a square body is carried out. Heat conduction performance comparisons of the bodies based on different optimization objectives and different layouts of the high conductivity channels are performed.
