Description
The effects of bulk viscosity on the elliptic flow ν2 are studied using realistic equation of state and realistic transport coefficients. We find that the bulk viscosity acts in a non trivial manner on ν2. At low pT, the reduction of ν2 is even more effective compared to the case of shear viscosity, whereas at high pT, an enhancement of ν2 compared to the ideal case is observed. We argue that this is caused by the competition of the critical behavior of the equation of state and the transport coefficients.
