Abstract
A heat exchanger for a turbine is provided wherein the heat exchanger comprises a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides. In addition, a plurality of concavities are disposed on a surface portion of the sheet of material so as to cause hydrodynamic interactions and affect a heat transfer rate of the turbine between a fluid and the concavities when the fluid is disposed over the concavities.

A heat exchanger for a turbine comprising:
- a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides;
- and
- a plurality of concavities disposed on a surface portion of said material so as to cause hydrodynamic interactions and affect a heat transfer rate of said turbine between a fluid and said concavities when said fluid is disposed over said concavities.
A gas turbine assembly comprising:
- a compressor;
- a combustor coupled to said compressor;
- a turbine generator coupled to said compressor;
- a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides;
- and
- a plurality of concavities disposed on a surface portion of said material so as to cause hydrodynamic interactions and affect a heat transfer rate between a fluid and said concavities when said fluid is disposed over said concavities.
