Scale-Adaptive Simulation on the Reactive Turbulent Flow in a Partial Combustion Lance: Assessment of Thermal Insulators

This paper presents a scale-adaptive simulation (SAS) of a partial combustion lance (PCL) aiming to evaluate the influence of thermal insulation on the performance of syngas combustion. Standard k–ε (SKE) and Reynolds stress model (RSM) were used for comparison. The combustion reaction was modelled...
