Abstract:

Through the design practice of a high-density electronic equipment, a flow network model of the entire system is then constructed by coupling MacroFlo w,which is based on Flow Network Modeling （FNM）, and Computational Fluid Dynamics （CFD）. Meanwhile, the design ideas of coupling FNM and CFD in ther rmal design are described, and the detailed flow distribution of air throughout the system are predicted. By the experimentally measured values, the app  roach is shown to be highly efficient, quick and cost effective compared with CFD only. It shows the future application of flow network modeling is pros  pected.
