The Impact

An experimental investigation was conducted to study the impact of component layout and geometry on flow distribution on a circuit pack. The experiment was conducted in a water tunnel using aluminum blocks to simulate various electronic components. The experiments were conducted for laminar and onset of transition Reynolds numbers. Diluted ink was used as the flow visualization vehicle. The study looked at flow over single component, multiple component, and fully loaded circuit packs. The study drew a number of conclusions including the flows were highly three dimensional, and location and orientation of components with large aspect ratio will significantly affect circuit pack flow distribution.

AbstractThe wake behind a cube with a face normal to the flow was investigated experimentally in a water tunnel using laser induced fluorescence (LIF) visualisation and particle image velocimetry (PIV) techniques. Measurements were carried out for moderate Reynolds numbers between 100 and 400 and in this range a sequence of two flow bifurcations was confirmed. Values for both onsets were determined in the framework of Landau’s instability model. The measured longitudinal vorticity was separated into three components corresponding to each of the identified regimes. It was shown that the vorticity associated with a basic flow regime originates from corners of the bluff body, in contrast to the two other contributions which are related to instability effects. The present experimental results are compared with numerical simulation carried out earlier by Saha (Phys. Fluids, vol. 16, 2004, pp. 1630–1646).
