Moreover, high contribution of convective heat transfer can be observed in the regions near the center of feed channel.
However, with an increment in the thickness of a thermal insulation layer of enclosures, convective heat transfer is formed in the air permeable insulation material due to difference in temperature and wind pressure through it.
