Title: Numerical Simulation on Structure Optimizing of Inlet Ducts in Gas-steam Combined Cycle Heat Recovery Steam Generators
Abstract: The 2-D and 3-D numerical simulation of flowing field in inlet ducts in gas-steam combined cycle heat recovery steam generators are made applying CFD soft ware FLUENT in this paper.The theoretical models are established based on k-e model.The method of discretization of models is Second up wind scheme.The computing method is SIMPLE.The heating surface in HRSG is made into porous medium.The velocity distributions at the outlet of inlet duct with different structure are obtained.The optimized inlet duct is proposed on the basis of the velocity distributions at the outlet.The comparison between the 2-D and 3-D numerical simulation results is made.
