ESTABLISHING CRITERIA FOR SIDEWALL AIR INLET PERFORMANCE AND EVALUATION OF FOUR COMMERCIAL INLETS ON THIS CRITERIA

S. J. Hoff, C. G. Wu
2000 Transactions of the ASAE  
Four commercially available sidewall air inlets and one sharp-edged rectangular opening were tested in a fullscale building section under similar isothermal conditions. Large differences were found between inlets for airjet spread, axial velocity decay, airjet throw, and entrainment ratio. A criterion was derived for evaluating inlets utilizing airjet throw, airjet spread, entrainment ratio, and animal-level velocity. The criterion developed highlighted some deficiencies of the commercially
