Hi Friends,
I am trying modelling DDT (deflagration to detonation transition). My first step was to create a uniform mixture of Jet A vapor and air which I have done successfully. During my second step I want to ignite this mixture to model DDT. While doing this I made a new case file. in this new file I changed the air and fuel inlets into wall, made a high temperature primitive region (to initiate ignition) and defining the reactions. While defining run I am using the result file of the previous simulation (mixture formation) trying to run it but it always end up with error. once it end up with Stack overflow then I reduced the time step. but it again stopped with error. For new simulation I am taking time step size as 10^6 sec and time duration of .001 sec. but still there is an error. Can someone tell me If this is the right way to go or what could be the possible mistakes? Please help... |
