Modeling of Synthetic Jet Ejectors for Electronics Cooling

This paper presents the modeling results for prediction of thermal performance using synthetic jets ejectors. A synthetic jet is an intense, small-scale turbulent jet synthesized directly from the fluid in which it is embedded. A jet ejector consists of a primary high momentum jet inducing a secondary flow within a channel. In the work presented here, a 2D synthetic jet is used as the primary jet causing secondary flow to be induced in a channel. The flow entrainment prediction for the model is based on the solution of mass and momentum equations within the channel. A resistance network model is used to predict the thermal performance. The modeling results are compared with data from past tests of synthetic jet cooling within channels as well as a completely integrated synthetic jet heat sink module.
