Investigation of the Effect of the Thermal Wall Thickness on its Back Surface Temperature for a Poultry Brooding Pen Heated by Trombe Wall

This study was undertaken to use computer simulation to determine the effect of the thermal wall thickness on the hourly temperature variation in the wall back surface of a large scale poultry brooding pen heated solely by the Trombe wall system. Trombe walls of thicknesses 20cm, 25cm, 30cm, 35cm, 40cm, and 45cm were investigated in this work. It was found that the back surface of the 20cm thick wall had the highest average temperature of 45.13.00ºC while the back surface of the 45cm thick wall gave the lowest average temperature of 34.58ºC. These values show that, in all cases, the optimum brooding temperature requirement could be obtained easily. From these results, it was concluded that the thickness of the wall has significant effect on the temperature of back surface .
