In most cases, however, this wear is restricted to the high-velocity areas of the rotor, such as the vane or blade tips, but can affect the entire assembly. Plate-out is a much more serious problem. The combination of particulates and moisture can form a ‘glue’ that binds to the ...
Precipitation mass was observed by the ARM Program using a laser disdrometer (LDIS), which measures the drop size spectra and fall velocity of hydrometeors during precipitation events88. Boundary layer height Boundary layer height (BLH) was calculated using meteorological profiles from radiosondes, ...
(height, diameter, plume velocity, and plume temperature) applying the Holland formula33, using ambient temperature and wind speed from the air quality model’s atmospheric layer that corresponds to the emission source’s stack height and location, and ambient pressure that we calculate as a ...

Later fuel spray nozzles utilize the airspray principle that employs high velocity air instead of high velocity fuel to cause atomization. This method allows atomization at low fuel flow rates (provided sufficient air velocity exists) thus providing an advantage over the pressure jet atomizer by ...
The exhaust velocity of the tracer gas in the wind tunnel test was set consistent to the velocity of exhaust gas in real condition. A flow gauge (NGX-PLATON), with a rate resolution of 0.2 L/min, was employed to stabilize the output. For the concentration measurement of tracer gas, the...
