For high-speed micro gas turbine plants for electrical power and heat generation, a recuperator is needed to obtain a high thermal efficiency. The recuperator receives heat from the exhaust gas and preheats the compressor discharge air before it enters the combustion chamber. Such plants contribute to an ecological and environmental-friendly energy production. (Muley, Sundén, 2003) This paper deals with the computer modelling of the recuperator where a commercial Computational Fluid Dynamics (CFD) code STAR-CD is being used for this purpose. The first part of the paper shows CFD ability to appreciate various heat transfer surfaces. Three different surfaces (cross corrugated surface, dimpled and rifled tube) are selected, modelled and compared. Next part of this paper describes the CFD evaluation of the required recuperator efficiency (92 percent). The last part of the paper considers simulations of the inlet/outlet manifolds where two construction variants are modelled and contrasted. Simulation results obtained are presented and discussed.
