hi, everyone!

i have a final project to simulate 2-D combustion chamber in turbojet engine (internal flow)
i wanna ask, what size of boundary layer that should i have?
i set the boundary layer : a = 0.0001
b = 1.5 (ratio)
rows = 20
in that value is difficult to be convergenced
is it ok? or i have to change some value?

i need advice from you all, many thanks

BrolY will become famous soon enough
The boundary layer height depends on the flow conditions.
You can find formula to calculate it on the help engine of your solver, or on internet.
