The mass production of carbon nanotubes (CNTs) must be premised for actual life. Recently, many studies have been conducted to closely examine the thermal and flow fields inside of the reactor for mass production of CNTs. In this paper, the radiation heat transfer effect is numerically studied for the multiple substrates with respect to the substrate distance. The computational results show that when the substrate distance is close, the temperature andflow film is observed due to the radiationheat transfer effect of each substrate. As the substrate distance becomes larger the radiation heat transfer effect decrease. When the three substrates are ready to grow the CNTs, the substrate distance is required to be less than 40 mm. Also, the back side of the first substrate, the back and front sides of the second substrate and the front side of the third substrate can be used to grow the CNTs at the three substrates.

Keywords:thermal CVD reactor;multiple substrates;substrate distance;CFD;radiation heat transfer
