Pressure Loss Coefficient Measurements of Two Close-Coupled HVAC Elbows
An experimental program was initiated to determine the friction factor in a straight duct and the loss coefficient of either a single elbow or two elbows placed in close proximity. The tests were performed in accordance with ANSI/ASHRAE Standard 120-1999. Loss coefficients C were measured for six kinds of single elbows. Likewise, identical pairs of elbows were considered in the close-coupled elbow experiments. For long separation lengths, the loss coefficient for two close-coupled elbows approached to within approximately 10% of the value of 2*C for a single elbow, for most cases considered in this study. The single-elbow data were also compared with those published in the 2002 ASHRAE Duct Fitting Database
