I need to simulate the flow field of the lagoon through software (e.g. CFD,Fluent,MATLAB ) ,which parameters should be investigated in the field? What do I do if I have these parameters?
3D simulations of a lagoon require solution of equations on a domain with a free surface, which is probably not available in FLUENT and may require development of specific code. The flow field is defined by free surface height, velocity profile over each discretization cell/element and possibly density or temperature profile as well, in case a baroclinic model is employed. The parameters that must be provided are friction and wind drag coefficients and some estimate of the turbulent viscosity. The data required, for tidal lagoons, are at least the tidal heights at the inlets and some other water elevation data inside the lagoon for basic validation.
