Design of a coldplate using Flow Network Modeling (FNM)

The present study describes the technique of Flow Network Modeling (FNM) and its application for the design of a coldplate. The technique of FNM involves representation of the overall flow system as a network of flow paths and flow components. It employs overall component characteristics solving momentum, mass, and energy conservation equations to predict system-wide fluid flow and temperature distributions. In addition, the use of empirical data and correlations for the flow component characteristics ensures good accuracy of the results. Experimental data from exit flow velocities show that the results from FNM are within approximately 20% of laboratory tests. Unlike other modeling techniques, the amount of time and effort required to create models and solve the problems is relatively low. Simplicity and ease-of-use make the FNM attractive in solving complicated flow systems. This ability to rapidly create and evaluate designs early in the design stage enables the quick development of a good system design
