  natural convection effect
     Both the numerical calculation and experimental results show that under the larger fluctuation of surface temperature, some natural convection effect will occur in the block stone specimen in closed system. And the cooling temperature effect has the accumulative property with time, but the heat transfer in the upper portion of specimen is dominated by the thermal conduction, so that the temperature wave amplitude attenuation in specimen is in accord with index law well.

Freezing around a vertical cylinder immersed in porous media incorporating the natural convection effect
      


In this paper, a mixed convection in a vertical porous channels with internal heat sources is numerically studied. The distribution of velccity, temperature and heat flux at various conditions are calculated, the results show that the flow reversal zones can appear near the two walls and these zones will move upstream with the increasing intense of the internal heat sources. The criterion for judging flow reversals can be obtained through FDF theory.

The heat transfer mechanism in the porous block stone specimens in closed-system and opened-system are analyzed. Both the numerical calculation and experimental results show that under the larger fluctuation of surface temperature, some natural convection effect will occur in the block stone specimen in closed system. And the cooling temperature effect has the accumulative property with time, but the heat transfer in the upper portion of specimen is dominated by the thermal conduction, so that the temperature wave amplitude attenuation in specimen is in accord with index law well. Therefore, the thermal conductivity of block stone for embankment and revetment can be determined using elongated specimens in closed-system.
