| Research Abstract |
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.
