Abstract

Experimental and theoretical studies on transient forced convection inside channels are reported, for both smooth ducts and passages with arrays of block-like electronic components. An experimental setup was built and used to study the thermal response in laminar flow within a parallel-plates channel, due to periodic time oscillations of inlet temperature, in terms of phase lags and amplitude decays with respect to the inlet condition. The theoretical results are obtained through extensions of the so-called generalized integral transform technique, which allows for an user prescribed accuracy due to its hybrid numerical-analytical nature. Theoretical results are validated by the experimental findings; sample results of this validation are presented, and recent results from the experimental runs for ducts with arrays of block-like electronic components are illustrated.
