Assessment of Periodic Flow Assumption for Unsteady Heat Transfer in Grooved Channels

Numerical studies of unsteady heat transfer in grooved channel flows are made. The flows are of special relevance to electronic systems. Predictions suggest a commonly used periodic flow assumption (for modeling rows of similar electronic components) may not be valid over a significant system extent. It is found that the downstream flow development is strongly dependent on geometry. @DOI: 10.1115/1.1833371#
