KIVA4 vs Fluent Simulation

raymond350 · April 15, 2013, 02:02

I am trying to see if KIVA could simulate liquid fuel combustion, and maybe compare its results with Fluent.

I tried to re-create the Fluent case file here using KIVA with a 3-D geometry.

As this is not a standard internal combustion engine case, there are a lot of input parameters in itape5 I can't figure out (after going through the internet and LANL manuals). It is not so straightforward like Fluent in setting Total pressure inlet, and pressure outlet, injection parameters etc.

Anyone out there can provide advice on this? Any help is greatly appreciated. Thanks.

If there is guidelines regarding itape5 parameters on how to start simulation with coldflow first, would be great as well.

i.e. set pressure inlet, and outlet boundary conditions.
