Abstract An atmospheric pressure non-equilibrium plasma (APNEP) jet has been developed and used to deposit thin ceramic films on ceramic substrates. The flow behaviour of the jet has been investigated using PHOENICS CFD package with the standard k-e turbulence model. It was found that the model gives encouraging agreement with experiments, and provides good understanding of the use of APNEP. Analysis of the coating surface using SEM, TEM, and XRD has been performed, revealing a nano-particle micro-porous surface structure, which should provide a beneficial surface mechanism for hot gas filtering technology. 1 Introduction Over 100 million tonnes of municipal solid waste (MSW) is prod
