Conventional and Air Assisted Distribution of Fine sprays in Still Air under a boom section of the Twin Force

August 17 99 data

In HAUC Machinery Hall August 17 1999

We believe that the ISO 02 nozzle was showing non uniform profiles and could be masking the effect of air assistance of the Force

Rather than present the pipe cleaners in groups of 4, we made up a 12 metre section of drift mast and put our clips on it at 100 mm intervals.

Single pipe cleaners were presented horizontally to the spray running along the swath to intensively sample the apparent nozzle distribution using a distance that would relate to the Scanner [SC to do Thursday]

Nine runs were made; ISO 02, Injet 03 and ISO 01 [at 3 bars] all without air assistance, with fans at 150 and 250 bars.

Spraying speed was 4 miles/hour [6.4 km/hour] jockey wheel was raised but boom was 54 cms above pipe cleaners.

Note: In general, as air speed increases with Force, so the mean deposit values rise and variability gets less.

It is encouraging that we see - as expected:

Overall values increase with decreasing drop size

ISO 02 more uniform than ISO 01 and Injet 03

Air assistance has this positive effect on such targets

Conventional and Air Assisted Distribution of Fine sprays in Still Air under a boom section of the Twin Force

August 17 99 data

In HAUC Machinery Hall August 17 1999

We believe that the ISO 02 nozzle was showing non uniform profiles and could be masking the effect of air assistance of the Force

Rather than present the pipe cleaners in groups of 4, we made up a 12 metre section of drift mast and put our clips on it at 100 mm intervals.

Single pipe cleaners were presented horizontally to the spray running along the swath to intensively sample the apparent nozzle distribution using a distance that would relate to the Scanner [SC to do Thursday]

Nine runs were made; ISO 02, Injet 03 and ISO 01 [at 3 bars] all without air assistance, with fans at 150 and 250 bars.

Spraying speed was 4 miles/hour [6.4 km/hour] jockey wheel was raised but boom was 54 cms above pipe cleaners.

Conditions: Spraying speed; 6.4 km.hourNozzle pressure; 3 barsBoom height: 540 mm

Note: In general, as air speed increases with Force, so the mean deposit values rise and variability gets less.

It is encouraging that we see - as expected:

Overall values increase with decreasing drop size

ISO 02 more uniform than ISO 01 and Injet 03

Air assistance has this positive effect on such targets
