In the 2-D numerical analytical method with original size model, try to change the height of the glass wall and the area of hole. In the 3-D numerical analytical methods with reduced size model, try to change the area of hole. The DPIV (Digital Particle Image Velocimetry) was also carried out in a reduced size model to compare the flow field s with the numerical results.  The experiment was used the DPIV with reduced size model to pick up a 2-D velocity field. we used two kinds of wall, which one has no hole and the other has two holes. The results indicated that the airflow move off the glass wall, it will spread into the atmosphere. When the glass wall has two holes, the part of airflow will pass through the holes. Compare with the 3-D numerical analytical and the experiment, the results were similar.  The Navier-Stokes equations with the energy equations were solved in this study. The SIMPLEC algorithm with finite volume based scheme was used in this numerical analysis. The results indicated that the height of the glass wall and the area of hole will influence temperature distribution in the glass wall, heighten the height of the glass wall and magnify the area of hole can reduce temperature in the glass wall of the incinerator air-cooled condenser.
