In order to compete with steel, a fibre-reinforced composite exhaust wall with a general-purpose resin system requires an effective but lightweight insulation layer. However a lack of experimental methods for heat transfer from turbulent gas flow to pipe walls lined with a porous insulation layer was discovered in literature. Such a test method is crucial to assess the influence of the permeability of such an insulation layer on the heat transfer rate, such that the lightest configuration can be selected. A new test method was developed and tested on samples representative for a composite exhaust. The accuracy of the method was assessed and the results for samples with different wall roughness were obtained. The behaviour of the samples under consideration proved to be more complicated than predicted by theories for impermeable pipe walls.
