A typical hybrid RANS-LES approach, DES (Detached Eddy Simulation), was introduced into cavitating flow simulation in this paper.
Menter, are assessed for the simulation of unsteady cavitating flow.
The purpose of this paper is to establish a dependable, robust and accurate computational CFD tool to analyze and minimize the cavitation effects in the design stage of fluid machinery components or systems.
In this paper, the scenario with natural cavitation number 0.6 and Reynolds number 7×105 is used for simulation.

For the simulation and the modeling of a fire several approaches are available [3-4], the most accurate, but computationally expensive one, is the computational fluid dynamics (CFD).
In this sense, an initial attempt applied to steel structures was done by Zhang in [5] who used the results obtained from the CFD simulation in a pure thermo-mechanical solver.
In particular, for the structural analysis a set of boundary conditions will be calculated from the CFD simulation, including both heat and mass transfer.
Further developments in this research, will include a “two ways” coupling with which the results obtained from the FEM analysis of the solid domain will be used as boundary conditions for the CFD simulation.
