Abstract
A one-dimensional hydrodynamic model of supercritical CO2(S-CO2) coupled with computational fluid dynamics (CFD) simulation of gas combustion is developed. The heat exchangers are introduced into the CFD simulation as energy/momentum absorption sources. Complex tube structures can be built with the aid of AutoCAD, and therefore the simulation could give detailed information of heat exchangers. Numerical simulation is performed for a 5MWe gas-fired S-CO2 test boiler. The calculation results are validated by the thermodynamic design data. Tube outside surface temperature, as well as S-CO2 temperature distributions are obtained.
