Abstract: Abstract The behaviour of droplets consisting of two different Praestol®; solutions impacting on a dry solid wall was studied. They show a similar but not identical spreading behaviour. This difference is due to the shear-thinning characteristics of Praetol®; 2540 where lower viscosities are reached for smaller shear rates compared to Praetol®; 2500. The results may serve as a basis for future comparisons with Newtonian liquids. The in-house code FS3D was used which is based on a Volume of Fluid method. The parallel performance of the code was analysed by studying the strong and weak scaling behaviour on the Cray CX40 system at the HLRS Stuttgart. Non-ideal speed-up was found which is mostly due to the high communication load in the multigrid solver. A new solver will overcome these limitations in the future.
