Radiative and conductive heat transfer simulation of window for solar receiver

In a solar tower receiver system, window for solar receiver emits radiative energy and absorbs radiation from concentrated sunlight, ambient and itself .In this paper, the radiative heat transfer of a semitransparent quartz window for a solar receiver is simulated by modified Monte Carlo method and finite volume method (FVM). It is found that the maximum interior temperature and temperature profiles are very sensitive to the depth of window and the inside temperature of air. However, the convective heat transfer between window inner side and air has a minor effect on the maximum interior temperature and temperature profiles.
