Understanding Bernoulli Loss in Fluid Dynamics

Click For Summary
SUMMARY

Bernoulli Loss refers to the energy dissipation in fluid dynamics due to turbulence, necessitating the inclusion of a head loss term in the Bernoulli equation. This loss is not addressed by the standard Bernoulli equation, which primarily focuses on energy conservation. Understanding Bernoulli Loss is crucial for accurately modeling fluid behavior in turbulent conditions.

"Bernoulli Loss"

Hi,

I am reading a fluid dynamics paper about dissipation due to turbulence in the fluid causing "Bernoulli loss". What exactly is meant by this? The Bernoulli principle concerns energy conservation. So, does Bernoulli loss simply refer to a loss of energy within the fluid (due to energy dissipation)?

Thanks

It means that when applying the Bernoulli equation to the fluid, you would need a head loss term to account for viscous dissipation because it is not covered by the standard Bernoulli equation. That isn't a very common term though.
