i came a cross an article saying that turbulent flow is one of the classical fluid mechanics problem which has not been solved.

The main problem is people is still not able to describe turbulent flow using derived equations based on basic physic such as the Navier-Stokes equations.

What is the reason that turbulent flow is so hard to be solved?

Wrong assumptions such as the flow is continuous, zero velocity at the wall? Unable to solve Non-Linear PDE? Computer limitation? Wrong approach?

Or Turbulent flow analysis is like the weather prediction which is decribed as chaotic?(Lorentz chaos theory)
