Rajesh Kumar Mishra

Till date I think the free software is not available over the network.

Maarten Cornelis Buijsman

Your question is too broad. In what field? In the field of oceanography, community models such as ROMS and MITgcm are good models to study regional to process scale water movement.

Leonardo Romero Monteiro

Free surface turbulent flows, that can simulate even the small scales.

mmm.. I know MITgcm can be run in nonhydrostatic mode up to pretty small scales (~cm if you like). However, generally this model is used for oceanographic applications of larger scales.
