This paper discusses a methodology for increasing powder deposition efficiency through the use of efficient nozzles for powder coating guns. The work utilised standard computational fluid dynamics software (FLUENT) to investigate alternative nozzle designs. Reverse engineering and rapid prototyping were employed to produce the candidate nozzles. Practical tests in a powder-coaling booth indicated significant improvement in powder deposition efficiency.


Powder coaling has attracted increasing industrial interest, mainly ...
