Fluid Dynamics Simulation (Thermal Simulation)

My name is Michael Riebel. I’m working at Fujitsu as a thermal design engineer and today I want tell you more about my daily work, which is called Fluid Dynamics Simulation or thermal simulation for short.
Almost every Fujitsu PC system has been thermally optimized with the 3D software of FloTherm. The early implementation of computational fluid dynamics software in the R&D process also avoids expensive delays.

Using thermal simulation it is possible to obtain valuable conclusions inputs in very early stages of the development process (e.g. proof of realization, optimization advice). It is also possible to investigate and rate multiple design alternatives without the cost of materials. That means a virtual system cooling device can be optimized before the real components are available and later the results of the simulation can be reproduced with real equipment.

The benefits are high. All results are archivable and available for the entire solution domain and provide a comprehensive overview of the flow conditions in the system. By contrast the measurements offer only values at preassigned checkpoints. Since the position of the sensors must be fixed in advance it might be possible that important values and effects are not monitored. Additional results such as temperature rise of the air while is streaming through the system are available without any extra effort (e.g. input for dimensioning of the air conditioners in data centers). All results can be shown in significant visualizations. The temperature and flow plots are like the animated flow videos well suited for pointing out the FTS R&D know-how within customer presentations and technical documentation.

Below you will find an example of a real thermal simulation. I filmed it from my desktop.

    This looks like useful technology for viewing the air flow through a machine. This could also be used for Data Centre as well and how the air flows through the building.

    Is this simlation software pice an own developement? I think the car industry is using something similar?

    @Marco The software is not our own development tool. We bought a professional software tool and its used in various industry branches which all have to solve cooling problems of electronics systems. Also the car industry and their suppliers are among the useres.

    Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are common tools that have been around quite a long time and are not the domain of any particular industry. I use It myself in my profession. It's always nice to see applications by others.
