Hello to all,
I'm bit confused about the impact of energy equation on the obtained results, namely: I have launched 2 analyses, one with total energy equation and second one without energy equation.
In both cases I'm simulating the flow of incompressible fluid (water) with constant fluid properties (viscosity/conductivity, density).
Finally i'm obtaining two different pressure drops.
My question is why? Since the fluid properties in both cases are the same (are not temperature depended) I would expect the same results...
Or it does impact on the turbulence ?
Thanks in advance for your suggestions.
Cheers, bob
