In the present study, a heat transfer simulation model for internal fluidized bed type solar reactor has been developed, and then we have shown the guidance for high -efficiency and scalable design of the solar reactor. The obtained results are as follows; 1) Radiative transfer equation can be solved by the spherical harmonics method. We found that this method is very efficient for solving the radiative transfer equation involving multiple light scattering. 2) A heat transfer model using volume fraction method has been developed by combining with the radiative heat transfer. The heat transfer model can simulate temperature and velocity profile inside the reactor. 3) An experimental visualization of solar reactor has been developed. By comparison with the simulation results, we could improve our simulation model. 4) We have re-designed new type solar reactor based on the above the findings.

在本研究中，开发了内部流化床型太阳能反应器的传热模拟模型，为太阳能反应器的高效和可扩展设计提供了指导。得到的结果如下； 1) 辐射传输方程可用球谐函数法求解。我们发现这种方法对于求解涉及多次光散射的辐射传递方程非常有效。 2）结合辐射传热，建立了体积分数法传热模型。传热模型可以模拟反应器内部的温度和速度分布。 3）开发了太阳能反应堆的实验可视化。通过与仿真结果的比较，我们可以改进我们的仿真模型。 4）根据上述研究结果，我们重新设计了新型太阳能反应堆。
