E-Filter L2 detailed
Created Wednesday 15 October 2014
Detailed model for an e-filter with dynamic energy and mass balances, taking convective heat transfer and pressure losses into account.
1. Purpose of Model
This model is used for the detailed simulation of an empirical electrostatic dust filter for flue gas cleaning purposes with a detailed calculation of the separation rate according to [1]
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [2], this model refers to the level of detail L2.
2.2 Physical Effects Considered
- Conservation of Mass
- Conservation of Energy
- Back flow
- Heat Transport due to convection
- Pressure loss due to friction
2.3 Level of Insight
Heat Transfer
- Basics:ControlVolumes:Fundamentals:HeatTransport:Generic HT:Adiabat L2 : No heat transfer

- Basics:ControlVolumes:Fundamentals:HeatTransport:Generic HT:Constant L2 : All Geo || HTC || Constant
- Basics:ControlVolumes:Fundamentals:HeatTransport:Generic HT:IdealHeatTransfer L2 : All Geo || Ideal Heat Transfer
Pressure Loss
- Basics:ControlVolumes:Fundamentals:PressureLoss:Generic PL:NoFriction L2: Friction free flow between inlet and outlet
- Basics:ControlVolumes:Fundamentals:PressureLoss:Generic PL:LinearPressureLoss L2 : Linear pressure loss based on nominal values
- Basics:ControlVolumes:Fundamentals:PressureLoss:Generic PL:QuadraticNominalPoint L2 Quadratic pressure loss, density independent
Geometry
- Generic_Geometry : Generic geometry
3. Limits of Validity
- Steady flow.
- Fixed control volume.
- Averaging assumption violated.
- The equations imply that the outlet states equal the states in the balance equations - Not true for large volumes and high gradients.
