16 ◾ Computational Fluid Dynamics Simulation of Spray Dryers temperature of the fluid. Determining suitable temperature will require the similar solution of the energy equation given below for a two-dimensional system. 11) The equation above may need to be modified for energy transfer due to water vapor transport (in the context of spray dryers) and energy generation due to turbulent viscous dissipation or due to the drying process. 2 How Is Turbulence Captured? A complete theoretical treatment on turbulent flows is beyond the scope of this book.
For the transient flow field delineated by the preliminary steady-state simulation, the next step is then to switch over to the transient simulation framework. The flow field from the initial steady-state simulation is then used as the initial solution to the transient simulations. In the transient framework, the flow field should then be allowed to numerically develop to reach a self-sustained transient behavior. Full development of the flow field can be monitored by continuous recording of the flow velocity at arbitrary locations within the chamber.
The buoyancy force is also incorporated but in a particle–air system, owing to the low density of air, this effect will be very minimal. This form of the force balance is commonly used in the spray-drying simulations for the range of particles size and airflow velocity found in spray dryers. Additional forces such as particle rotation or thermophoretic forces can be easily added into the computation if required. Particles collisions are normally neglected owing to the low particle loading in the system, unless agglomeration or coalescence modeling is adopted.
