Turbulent flow : visualization

Even if we have not studied turbulence, we already know a little bit about it. We already have seen the chaotic motion of turbulent flow: seas, rivers...etc. In geophysics, turbulence is the dominant physical process in the transfer of momentum and heat. It diffuses the solutes and small organic particles, in lakes, seas, oceans, atmosphere. Turbulence in fluids is perceived as a primary chaotic motion with all degrees of freedom excited.
