High Re K Epsilon vs Low Re K Epsilon Backstep

Hi folks,

I am somewhat new to CFD (only been doing for some months ), and I have a doubt which I hope some can clear...

I am trying to implement a Low Re K-Epsilon turbulence model to a backstep and compare it to a High Re K-Epsilon turbulence model, to show that, in this particular case, the Low Re K-Epsilon turbulence model represents the situation better.

However, I get a pressure drop that is higher for the Low Re K-Epsilon turbulence model than the pressure drop for the High Re K-Epsilon turbulence model...

Is this correct? shouldn't it be the opposite?
Or perhaps I made a mistake in the modelling step?

Hope someone can help!

Best Regards,

Rui Silva
