Numerical investigation of the hydrodynamic amplification and thermal instabilities by imposing pulsation during forced convection of air cooling of nine identical heated blocks mounted on a horizontal channel is presented. The finite volume method has been used to solve the governing equations. The feature of this work is a narrowband of frequencies, where the enhancement of heat transfer of all electronic components is in the range of 25%–55% compared with steady nonpulsation flow is obtained. Good agreement between numerical simulations and experimental results available from the literature is obtained.
