Abstract

v-USPhydro is a new relativistic 2+1 Lagrangian hydrodynamic code that incorporates the effects of bulk viscous hydrodynamics using Smoothed Particle Hydrodynamics (SPH) and is applicable to heavy ion collisions. Within this framework the bulk viscosity effects on collective flow harmonics i.e. v 2-v5 are studied on an event-by-event basis. We discuss which corrections to the Cooper Frye model are most appropriate when bulk viscosity is considered. An enhancement of all the Fourier harmonics is seen when bulk viscosity correction to the Cooper Frye is considered even when the bulk viscosity to entropy density ratio, ζ/s, is significantly smaller than 1/(4π).
