We report on recent results from VISH2+1, a code that solves the relativistic Israel-Stewart equations for causal viscous hydrodynamics for heavyion collisions with longitudinal boost invariance. We find that even “minimal” shear viscosity η/s = ~/(4π) leads to a large reduction of elliptic flow compared to ideal fluid dynamics. We explore systematically the sensitivity of this reduction to the...

The study of fluid dynamics has applications in many areas of engineering and science. This includes the understanding environmental, biological and chemical flows. Laboratory experiments and computer simulations are the two main approaches for the study of complex flow problems. Computer simulations can help one to understand and analyse the complexity involved in these flows more clearly with...
