Abstract

Multiscale coupling techniques are a useful tool needed to simulate complex and huge physical domains. In particular they can be used when a full 3D simulation cannot be performed due to high computational cost or when one is not interested to accurate 3D details of the whole system. In the present paper we focus our attention on the data exchange between different computational domains and present preliminary results obtained from the coupling of 3D and 2D simulations of a power-cooling system. This multidimensional configuration is coupled with a simple 1D closed loop which overlaps the multidimensional domains. The CFD simulations correct the pressure losses and the temperature field of the 1D solution by using the defective method technique. The multiscale coupling is performed with the aid of the numerical platform SALOME and the MED library. The procedure for the coupling can be also used with different codes to perform complex simulations.
