Abstract
Compact Heat Exchangers are often used for cryogenic, air cooling and
automotive systems. Indeed, they are able to transfer high amount of heat while
keeping low volume and weight. The design of new geometries involves precise
knowledge of local phenomena such as momentum and energy transfer through
turbulence. Since few predictive models issued from experiences are available and
their accuracy limited, numerical simulation is more and more used. However,
because the flow is dominated by separation, recirculation and reattachment, the
precise simulation of the non-stationary phenomena is at the moment quite
complex. This work is devoted to the study of the flow and phenomena in
geometry of serrated fins. A good ag
