If you have the latest version of FDS, search the User's Guide for "Scaling Pyrolysis". |

good morning, I studied section 9.1.4 of the manual and built on the basis of the file spyro_cone_demo.fds the file you find attached in which I entered the parameters related to sugar that I found in the literature (calorimetric cone test with flux equal to 35kW/m2 test size 100x100x25mm and results you see in the graph below for sucrose) Many many thanks !!! |

Good morning, everyone. I'm new to FDS and I have a question about determining the HRR curve to be included within the calculation model from the results obtained at the calorimetric cone. How can I use the results of the test to determine the HRR curve to be entered into FDS? The sample tested had dimensions of 100x100x25mm, while the sugar, in my case, was deposited in bags of about 1x1x1m. How can I determine the HRRmax and the trend of the curve for the bag, given that the dimensions are completely different from that of the sample? Should I build an ad hoc FDS model by simulating the calorimetric cone test and then set the material characteristics in the general model? Or should I do it another way/simplier way?
Thank you very much.
