CFD Analysis of Condensation Process Occurring Inside High Efficiency Boilers

•Finned tube area modeled using porous media; a sub-model is used to determine the proper C2 (pressure drop) and porosity (conductive heat transfer) values.
•Simultaneous modeling of water flow on water side and combustion coupled heat transfer on the flue gas side.
•Heat transfer enhancement on the flue gas side due to water vapor condensing on the heat exchanger surface modeled using in-house UDF.
