We solve Navier-Stokes equations in the fluid phase and energy equation in both solid and fluid phases using a commercial CFD software: StarCCM4+ by CDAdapco.
Table 2 presents inertial and viscous parameters calculated from present simulation along with available literature data obtained for similar foam.
However, this local simulation gives us a fair insight of thermal performance for heat exchanger unit design.
Conclusion and Perspectives We predict important parameters relative to foam use in heat exchangers using simulation at pore scale on real topology.

Designers are now able to do complex simulations of the proposed systems in order to achieve the best possible solution with computation fluid dynamics (CFD), daylighting, and thermal transfer programs.
The technology is far advanced, but may not be there yet, as Moloney’s claims that the design simulation to achievable construction is complicated by the kinetic requirement [6].

It is a promising technology which integrates the CAD, CAE and virtual simulation technology.
Years before, due to the inefficiency in converting the data and integrating the information between the ship designing CAD system and the simulation analysis CAE software, it was unable to establish the connected relationship between the geometrical models and simulation analytical models so that the models could not be directly applied in the engineering analysis and calculation, this is called Information Island.
Through the converting and processing of the geometrical model (including the conversion of the model data format, the simplification of the model, the meshing, the process of the model boundary and so on), it is effective to generate the ship product simulation analytical model, perform analysis and calculation in the simulation analytical software and analyze or evaluate the design result, found in the literature [1].So, the 3D design model is set as the main model while the simulation analytical models of other disciplines which are derived from the main model are set as the connected models.
These pack the fundamental task elements that are from the work of product design, modeling, analysis and simulation.
With one example ship designed on the platform, we conducted the preliminary analysis of general performance, realized the integration of tools such as CATIA, FLUENT, NASTRAN etc., built parametric hull form surface and ship structural model, set the data connections among CAD, CAE and CFD and formed the template database of the fixation and accumulation of the knowledge and experience.
