Low-Flow Nozzles for Corrosion Spray Testing

Engineering Asked by Lord of Hours on February 13, 2021

So, for a cyclic corrosion test system, I need a nozzle or arrangement of nozzles that provides a flow rate of 45ml-140ml of salt solution per hour to an area 60cm square. All commercial nozzles I’ve been able to find with non-flat spray patterns have much higher flow volumes. Does anyone know if a specialty supplier for this type of equipment?

Also, I need to ensure that the area is saturated as evenly as possible – what sort of FEA or simulation program would be best for analyzing the distribution of mass/fluid in a spray arrangement?

Why not just use a standard salt spray cabinet ? I am sure it can use different salts other than sea salt. Those we had were roughly 4 ft. cubes which may be big for your work , but may have future uses. And a standard unit results are easy to compare to literature and/or publish. And as a standard unit it would have some resale value. I don't remember the particular manufacturer but it was some years ago and they have probably changed names.
