Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.
The system development with experimental studies that is
accomplished by trial and error method is neither practical nor
economical since it is difficult and expensive. So that, creating
the mathematical model and determining the most appropriate
design data by using numerical solutions is a more effective
and cheaper approach for the system development. In this study
numerical and experimental analysis of forced convection heat
transfer from the horizontal and lateral surfaces of a 0.3m x
0.3m x 0.52m rectangular box in a 0.55m x 0.55m x 3m wind
tunnel, which is heated by a 0.5m length cylindrical 450 W
power source with a constant surface temperature of 200ºC,
was performed. The temperature distribution on all exterior
sides of rectangular box subjected to forced convection, were
calculated by finite volume numerical analysis and compared
with the results obtained from the experimental measurements.
The main objective of this study is to verify the mathematical
model which was constituted for the numerical solution. The
results obtained from the numerical analysis were
approximately similar to the ones obtained in experimental
analysis, so the mathematical model was verified.
