In a previous paper, we reported the characteristics of transient heat conduction of slabs with natural convective voids. In the present paper, we analyzed the characteristics of the slabs withforced convective voids. This analysis simulates the practical case that they are used as air conditioning duct spaces.The simulations were carried out for two cases : i. e., the all day air-conditioningmode and the intermittent air-conditioning mode, in which the voids are used as the ducts for 10 hours continuously a day. In addition, the heating and cooling modes were considered for both air-conditioning modes.To study the effects of the heat transfer at the surface of the void on the overall heat conduction, we changed void air velocity into five values and the void surface emissivity into two values.The calculations of the heat flux, mean surface temperature and void air temperature in the different cases were compared.
