Non-isothermal flow of a Johnson-Segalman liquid in a lubricated pipe with wall slip

► Reacting flows of viscoelastic fluids are a model problem in the process industry. ► We investigate the dependence of flow quantities on wall slip in a typical such pressure driven flow in a pipe. ► We observe a strong relationship between wall slip and shear banding in non-isothermal pipe flow of Johnson-Segalman fluids. ► The fluid temperature (and hence susceptibility to thermal runaway) and velocity both increase with wall increasing slip. ► For shear banded flows, higher fluid viscoelasticity leads to increased susceptibility to thermal runaway phenomena.
