Focus is brought to industrial scale applications in the field of environmental engineering. A transient 3D finite volume solver is used, wherein the disperse phase is modeled within an Lagrangian framework. Two-way mass and enthalpy coupling is taken into account. Resulting limitations of the traditional sequential model droplet integration approach are discussed, which potentially lead to thermodynamically inconsistant or oscillatory solutions, especially in zones of dense spray. As an alternative a combined sequential-simultaneous solution algorithm is proposed. Thus obtained results show sufficient aggreement with a validated test case. Application to industrial scale reactors in the field of flue gas cleaning are demonstrated exemplarily.6 pagesPDFenUniversity of PretoriaUniversity of PretoriaEnthalpy couplingTransient 3D finite volumeIndustrial scale reactorsFlue gas cleaningPresentation
