Calibrating the CFD model by experimentation for Power Supply Design

An accurate CFD simulation depends on building an accurate thermal model. However, it can easily turn into an inaccurate model due to software pitfalls, misunderstanding component characteristics and incorrect physical product measurements. This paper focuses on providing guidelines in producing an accurate thermal model. These simulations as a result of considerations provided in this paper will produce results, which are very close to actual physical measurements. In this paper, we will provide from an engineering point of view, some practical projects and some special tests to build an accurate CFD model which matches the physical unit performance as close as possible. In addition some guidelines are provided to improve the measurement accuracy in the experimentation.
