Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
The method of computational fluid dynamics (CFD) is
applied to spraying processes with strong enthalpy coupling.
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
