Diamond Jet Air Flow

[Hunter85]

I am new to running a DJ2600 system. Can you tell me if there are any published works discussing the effects of increasing / decreasing the Air flow in this Gun. All of the parameters that I see have the Air flow at 44% to 50%.

Thanks for your help.

Hi Hunter85

to the Surface Engineering Forum.

Not been able to find much on this topic. Nearly all publish parameter optimisation work I've come across tends to concentrate on fuel/oxygen flows/ratios, spray distance and spray rates as the variable factors. Air flow for some reason is usually set as a constant from recommended parameters. Air flow is a critical parameter, apart from providing cooling to the air cap, it will influence gas/particle velocity/temperature. It will also influence any tendency for air cap fouling.
