Abstract: A heat exchanger includes a plurality of channels and one or more active flow disruption members disposed at an entrance to the plurality of channels. The active flow disruption members are configured to induce unsteadiness in a flow through the plurality of channels to increase thermal energy transfer in the plurality of channels. A method for transferring thermal energy from a heat exchanger includes locating one or more active flow disruption members at an entrance to a plurality of channels of the heat exchanger. A flow is directed across the one or more active flow disruption members into the plurality of channels and an unsteadiness is produced in the flow via the one or more active flow disruption members. The unsteadiness in the flow increases the transfer of thermal energy between the heat exchanger and the flow.
