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

Abstract

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 .
