Unsteady forced convection in a rectangular duct with arrays of block-like electronic components.

Author(s) : SOZBIR N., GUVEN H. R., SARAC H. I., KAKAC S.

Summary

An experimental investigation is carried out to study the behaviour of unsteady forced convection in a rectangular duct with arrays of rectangular modules attached to the lower wall. The modules are positioned both inlined and in staggered arrangements to simulate the cooling of electronic components. The investigation is conducted in both laminar and turbulent forced flows with approach Reynolds number ranging from 1120 to 22300, while the inlet heat input frequency varied from 0.02 to 0.24 hertz. The experiments are carried out in the thermal entrance region with the fully developed velocity profile. The temperature variation at several locations along the duct was measured and recorded. Temperature amplitude decayed exponentially along the duct. The decay indexes are obtained under different conditions.
