Dear all ,
Kindly can you help me in some of issues related to simulate combustion process in diesel engine with dynamic mesh ?
i use Ansys -Fluent (version 15) from about one year to make this simulation as a part from my study in master degree, but usually i don’t reach to my goals from this runs.
i made a run for motoring case and graph P- Theta and T-Theta for maximum pressure around 35 bar and Temperature about 1000 k. After that (this from around 6 months) i add injection before at around 340 Crank angle degree (CAD) which means before Top Dead Center (TDC) by 20 CAD and the surprise there is no any sudden change in pressure and temperature , almost you can say similar to motoring case in graph and values. By check temperature - fuel species distribution it appears un logic distribution, in addition to some errors usually appears with run such as divergence in AMG solver : Species or temperature .... etc.
Noteworthy i make change for almost all parameters in injection ( flowrate - injection speed - injection CAD duration - Injection Diameter - Inert or droplets ,,,etc.)
Realy i exhausted and fell very bad . Can any one help me in this issues, this help realy will chancge my life becouse there are alot of things paused till finish this master study
your fast responce is appreciated
Thanks
