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.

A composition of a zeotropic mixture has a first chemical constituent and at least one second, different chemical constituent. The zeoptropic mixture has a temperature glide of 5&#xb0; C.-25&#xb0; C. with regard to its saturated vapor temperature and its saturated liquid temperature. The first chemical constituent is selected from 1,1,1,3,3-pentafluoropropane, 1,1,2,2,3-pentafluoropropane, 1,1,1,3,3-pentafluorobutane, methyl perfluoropropyl ether, 1,1,1,2,3,3-hexafluoropropane and 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone.

An example power generation system includes a vapor generator, a turbine, a separator and a pump. In the separator, the multiple components of the working fluid are separated from each other and sent to separate condensers. Each of the separate condensers is configured for condensing a single component of the working fluid. Once each of the components condense back into a liquid form they are recombined and exhausted to a pump that in turn drives the working fluid back to the vapor generator.
