In general I like to plot contours of non-dimensionalized eddy viscosity. Since you may be close to sea level, you can non-dimensionalize your eddy viscosity by the sea level value of the dynamic...

I usually look at the eddy viscosity since eddy viscosity is created where the turbulence model thinks there is turbulence. Of course the turbulence model could be wrong... You can also check out...

Truthfully, I'm not sure what the pitfalls of our choices are. 1) yes defining the reference length is challenging. I don't think there is a good answer. That is part of the art. 2) The eddy...

Because of the small Reynolds number, I am assuming that the flow features are large-ish when compared to geometry scales. Fluentmonkey should say more about what he is modeling to give a better...

The use of a turbulence model will have an effect, how much depends on the level of the eddy viscosity compared to your laminar viscosity. If the ratio is...
