Abstract

The homogeneous coating of a flexible film that is applied to dye-sensitized solar cells is related to the performance and durability of the product. The applied coating is obtained from the uniform temperature distribution and the mass flow rate in the nozzle of the hot air dryer. In this study, we determine the uniform temperature distribution and mass flow rate of each nozzle by performing numerical simulations to understand how various factors affect the performance of the hot air dryer. The numerical model is composed of the momentum equation for flow motion and the energy equation for temperature. In addition, we compare the numerical results to the experimental results to validate the model. Based on the results, the round-hole plate inside the hot air dryer significantly affects the uniform temperature and the mass flow rate.

염료감응형 태양전지용 플렉시블 필름에 도포된 코팅물질의 균질한 코팅은 제품의 성능과 내구성과 매우 밀접한 관계가 있고, 균질한 코팅은 열풍건조로 노즐에서의 균일한 온도분포와 질량유량에 의해 얻어질 수 있다. 본 연구에서 열풍건조로의 성능향상에 영향을 주는 다양한 인자들에 대한 수치해석을 수행함으로써 열풍건조로 출구의 균일한 온도분포와 질량유량을 얻고자 하였다. 수치해석 모델은 유동방정식과 에너지방정식으로 구성되었고, 수치해석을 모델의 검증을 위해 수치해석 결과값과 실험결과를 비교하였다. 연구결과로서 열풍건조로의 타공판이 균일한 온도분포 및 질량유량에 큰 영향을 미친다는 것을 알 수 있었다.
