In order to do this I first had to suppress the glass tube that would hold the water back.&#0160; This simulates the heat from a fire expanding the liquid inside and breaking the glass.&#0160; Before being able to run the simulation I needed to make a containment part around the head of the sprinkler and also put a lid on the open end by the threads.&#0160; This was done in order to run the analysis as an internal flow.&#0160; To set up the actual simulation I first set up the computational domain so that it was a little larger then my whole assembly.&#0160; For the general settings I set the analysis type to internal, the fluid to water, and left the rest of the settings to their defaults.&#0160; From there, I needed to set up my boundary conditions.&#0160; These specify what the input and outputs to the system are.&#0160; For the input of the system, I selected the inside face of the lid and used a static pressure that was in a normal direction to the lid.&#0160; I then selected the internal faces of the containment part and set those to the environmental pressure which I left set to the default.&#0160; I also set the faces that were in the direct line parallel to the lid as an ideal wall.&#0160; From there I meshed and ran the simulation.&#0160; Once it had finished solving I inserted a flow trajectory using the internal face of the lid with 500 points showing the pressure of the water.&#0160; This is seen in the image above.&#0160; The result has some abnormalities that aren\u2019t what I expected&#0160; but that could be caused by how I set up the simulation.&#0160; I hope you enjoy.<\/p>\n<p>&#0160;<\/p>\n<p>Ian Jutras<\/p>\n<p>Worcester Polytechnic Institute<\/p>\n<p>Mechanical Engineering 2013<\/p>\n<p><span class=\"asset  asset-generic at-xid-6a00d83451706569e201676060ea4b970b\"><a href=\"https:\/\/solidworks.typepad.com\/files\/fire-sprinkler-with-simulation.zip\">Download Fire Sprinkler with simulation<\/a><\/span><\/p>\n<p>&#0160;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For this post, I decided to take the fire sprinkler that I posted on December 18th and run a flow simulation with it.&#0160;
