The appearance of travelling-wave-type solutions in pipe Poiseuille flow that are disconnected from the basic parabolic profile is numerically studied in detail. We focus on solutions in the twofold azimuthally-periodic subspace because of their special stability properties, but relate our findings to other solutions as well. Using timestepping, an adapted(More)
Many industrial, chemical and catalytic processes rely on oxides of alkaline-earth metals with high surface area. Among these oxides, magnesium oxide serves e.g. as cement additive, fi re resistant insulation as well as for adsorption and deacidifi cation in the rubber industry. Due to its unique surface chemistry, MgO is also employed as catalyst support(More)
