Hello,

I could not figure out the reasons for the water spray in my simulation becoming unstable when I make the mesh size smaller. I hope the community can point me in a direction for diagnosing this issue. I have included a video for your viewing. If you need the files, I can post them also. The mesh size is 2.5 cm x 2.5cm x 2.5cm.

Following is my set up:
+ dieselFoam for water spray (10 micron min and 50 micron max droplet dia)
+ nozzle dia = 3 mm
+ injection velocity = 10 m/sec
+ mass flow rate = 0.04241 kg/sec
+ injection pressure = ~1.5 bar
+ room size = 4 m long x 2 m high x 2 m wide with ambient air temp (300K ) and ambient pressure

I used VirtualDub (free and portable video editing software) to compress and crop the file.

Thank you for your help.
