Validation of spectral gas radiation models under oxyfuel conditions – Part C: Validation of simplified models

CFD and experimental analysis of a 115kW natural gas fired lab-scale furnace under oxy-fuel and air–fuel conditions

“…681 Furthermore, it can be seen that the prediction of the heat flux is 682 better for lower temperature levels (1070°C) than for higher tem-683 perature levels (1200°C). The deviation between the measurement 684 and calculation is in accordance with investigations done by 685 Becher et al [25]. In the investigation they compared the …”

Numerical investigation on oxy-combustion characteristics of a 200MWe tangentially fired boiler

“…Their study focused on the combustion mechanisms or gas radiative models, but did not carry out detailed investigation on the combustion and heat transfer properties. The series of articles by Becher et al [19][20][21] validated the accuracy of existing spectral gas radiative models for oxy-fuel combustion, by comparing them to line-by-line model based on HITIMP2010. [22] The WSGG model from Johansson et al [23] was recommended for calculations of spectral gas radiation in large-scale oxy-fuel combustion simulations.…”

A full spectrum k-distribution based weighted-sum-of-gray-gases model for oxy-fuel combustion

“…WSGG model is easy to incorporate into a CFD code. Considering computational costs, it may be the best selection in 3D full-scale simulations [17].…”
