3In Fluid dynamics derivatives -gt very
small Main contributions come from low momentum
and low energy modes Many theorists hope that
the Conformal fluid dynamics and fluid dynamics
have same universal features. Can we explain
fluid dynamics systems by black hole physics?
4There were many works and results about fluid
dynamics Our Approach follows arXiv0712.2456
