Spray Drying CFD Simulation

To simulate the present model, we consider several assumptions:

  • The solver is pressure-based.
  • The present simulation is unsteady in terms of time.
  • The gravity effect is equivalent to -9.81 m.s-1.

Here is a summary of the steps for defining the problem and its solution in the following table:

Viscous model K-epsilon realizable
Discrete phase on
particle treatment unsteady particle tracking
material in injection Water_liquid

Inlet Draying_air Velocity inlet
velocity magnitude 6 m.s-1
discrete phase BC type Escape

feed Mass_flow_inlet
Mass flow rate 0.0116kg/s
Thermal 300k
discrete phase BC type Escape
Outlet Pressure outlet
gauge pressure -150 Pascal
discrete phase BC type escape
walls Wall

discrete phase BC type reflect
Solution Methods
Pressure-velocity coupling   simple
Spatial discretization pressure second-order
momentum second-order upwind
Modified turbulent viscosity first-order upwind
Initialization method   hybrid


In this simulation, a spray dryer chamber is simulated. Due to the water droplets entering as particles and the heat transfer, the water droplets evaporate over time, and their diameter becomes smaller, which indicates the Spray Drying device performance.
