E-Filter L2 simple
Created Wednesday 15 October 2014
Model for an E-Filter with dynamic energy and mass balances, taking a constant separation rate into account.
1. Purpose of Model
This model is used for the simulation of an ideal electrostatic dust filter for flue gas cleaning purposes with fixed separation rate.
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [1], 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

- 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.
