Výpočtové modelování vlastností rekuperátoru spalin

CFD MODELING OF CROSS CORRUGATED MICROTURBINE RECUPERATOR

conference paper

en

The CFD code STAR CD was used to assess the thermal and hydraulic performance of a primary surface type gas turbine recuperator, with Cross Corrugated (CC) surface. The main goal of CFD modeling was to evaluate heat transfer and pressure drops predicted by the 1D methodology and thus to verify the recuperator efficiency. Two computational domains were made. The first for heat transfer and pressure drops simulation in the recuperator core and the latter for pressure drops predicted at the inlet and outlet ports. Details of the recuperator core, computational domains and the boundary conditions for CFD simulation as well as relevant results are presented.

Článek se zabývá výpočtovým modelováním hydraulických a termomechanických vlastností vysoce účinného rekuperátoru spalin spalovací turbíny. Pro voštinovou konstrukci teplosměnné plochy jsou vytvořeny dva výpočtové modely, které jsou následně analyzovány pomocí komerčního kódu STAR CD.
