Summary | 0001014: [ReitzKHRT]: Incorrect (stripped) parcel mass | ||||
Description | The stripped parcel mass 'ms' becomes negative for some parcels, something I believe should never happen. Also, the stripped parcel mass may reach values magnitudes higher than the parent parcel mass (e.g. ms=1e-8 vs. m=1e-12). I believe there is going something wrong with the particle vs. parcel mass and the update of mass0 (done for the child droplets in SprayParcel.C). | ||||
Steps To Reproduce | The issue can be observed when CRT is set to higher values (e.g. CRT=5.33 as used by Su (1996) or Patterson (1998)). | ||||
Additional Information | Su, T.F.; Patterson, M.A.; Reitz, R.D.; Farrell, P.V., "Experimental and Numerical Studies of High Pressure Multiple-Injection Sprays," SAE Paper 960861, SAE Transactions, Vol. 105, Section 3, Journal of Engines, pp. 1281-1292, 1996 Patterson, M.A.; Reitz, R.D., "Modeling the Effects of Fuel Spray Characteristics on Diesel Engine Combustion and Emissions," SAE Paper 980131, SAE Transactions, Vol. 107, Section 3, Journal of Engines, pp. 27-43, 1998 | ||||

I just remembered that I reported this some time ago when I reported bug #1295. Just to note, the stripped parcel mass calculation in the ReitzKHRT model is still wrong in my opinion, also with the suggested changes in my recent bug reports. |

Can you provide a patch to OpenFOAM-dev to resolve this problem? |

Please reopen this report if you can provide a patch or at least a test-case which reproduces the problem. |
