Digital Optimization of Hydraulic Filter Media
PDF tutorial
The performance of a filter is largely determined by three parameters: pressure drop, filter efficiency, and dust holding capacity (DHC). In practice, these properties influence each other—improving one property can have a negative effect on the others.
With GeoDict software, filter media can be modeled and simulated to find the optimal balance between these target variables. This saves development time and reduces physical testing.
In this PDF tutorial you will learn step-by-step:
- Understanding interrelationships: How pressure drop, filter efficiency (including β ratio) and DHC influence each other.
- Modeling filter structure: Design and variation of digital filter media with constant initial pressure drop and defined efficiency (β = 200 for ≥ 22 μm).
- Increase DHC: Simulation of dust absorption until a limit pressure drop is reached – with a focus on maximizing operating time.
- Ensure comparability: All structures start with identical base values for efficiency and pressure drop in order to objectively evaluate optimizations.
The aim of the tutorial is to develop a digital filter design that enables high particle capture without compromising pressure drop and efficiency.
