Analysis of electrostatic filter to mitigate ash diffusion into engine
Between March and June 2010 a series of volcanic events at Eyjafjallajökull in Iceland caused enormous disruption to air travel across Western Europe. The disruptions started over an initial period of six days in April 2010. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travelers. Volcanic ash has been caused grounding of many aircraft as a source of possible damage to aircraft engines. The projected technical strategy, an electrostatic precipitator (ESP), was tailored for the high bypass turbofan engine model PW4000 in this study. It was based on the standard two-stage ESP but designed with the PW4000 engine. The innovative ESP prototype is primarily made up of a hexagram structure of six discharge electrode plates and three circular collecting electrode rings. An aerodynamic verification was conducted through computational fluid design (CFD). It built a 20-meter wind tunnel and placed the engine with ESP in the centre of it. A particle-laden atmosphere was created in the simulation using a discrete phase model (DPM) to replicate volcanic ash injection into clean air. From the results, it has a clear aerodynamic impact near the engine's intake, although the effect is small and may be ignored after the engine fans. Additionally, a CFD electrostatic verification was generated with a voltage of 20000 V, and the contour of the electric potential is perfect distributed, suggesting that an electric field can be adequately given by this ESP configuration design. Therefore, the simulation results of the new ESP layout would have allowed drawing conclusions about the electrostatic filter's ability to reduce volcanic ash intake in an engine with high aerodynamic performance.
