Summary | 0001058: LTSReactingParcelFoam with coneNozzleInjection producing abnormal spray pattern | ||||
Description | Hi! I would like to report a repeating problem I have with a simple water spray in a cylindrical pipe. I specified a conical spray pattern in reactingCloud1Properties and checked many times to make sure I have the correct parameters. The result I obtained with LTSReactingParcelFoam is not what I expected. The spray does not have the cone shape but instead it appears to be injecting on a 2D plane whereas the domain is 3D. Attached is the screenshot of cross section of cylinder. As you can see, instead of a cone shape, its point of injection seems to be 2D (on Y-Z plane). I took this screenshot with paraview. Your help on this is much appreciated. | ||||
Steps To Reproduce | Create a cylinder (or any shape) as a domain. Run RAS turbulence model to obtain a solution first, and then run LTSReactingParcelFoam for 200 iterations. The residuals were in the 1e-8 to 1e-9. | ||||

Could you please supply a test case which reproduces the problem in OpenFOAM-2.3.x? |
