Abstract
1. The sensible heat transfer from a physical model of an adult fowl was investigated for the range of air speeds encountered in poultry houses in the United Kingdom, 0.09 to 2.7 m/s, equivalent to Reynolds numbers (Re) from 103 to 3 × 104. The Grashof number (Gr) range studied was from 6 x 106 to 107. 2. The pooled results were analysed to give a relationship between the Nusselt number (Nu) and Re in the mixed convective regime of: A combination of Nu, Re and Gr did not produce a better fit to the results. 3. Enhancement of heat transfer observed when Re was close to 103 was probably caused by an interaction between the forced and natural air currents.Keywords
