Abstract

Experimental and numerical modeling were conducted to determine the dust concentration distribution in a simulated, mechanically ventilated, swine nursery room under non-isothermal conditions. Effects of dust generation rate, temperature difference between supply air and inside air, dust source location, and presence/absence of obstructions (mock pigs) on dust concentration were also evaluated. Results from numerical modeling agreed well with measured values from full-scale tests, based on the ASTM (1995) guidelines. Analysis of the measured values indicated that the dust source location significantly (p < 0.05) influenced the dust concentration distribution; dust concentration was higher at or near the source. However, the effects of temperature difference between supply air and inside air (7.0 vs. 16.0°C), dust generation rate (low vs high), and presence/absence of the mock pigs on dust concentration distribution were not statistically significant (p > 0.05).
