Quintessence Model Calculations for Bulk Viscous Fluid and Low Value Predictions of the Coefficient of Bulk Viscosity

Shouvik Sadhukhan


Abstract: In this paper I have used the idea of bulk viscosity of fluid in FRW model and applied this idea into Quintessence to discuss about the cosmological inflation system. I have tried to derive the slow roll mechanism and to match it’s result with the inflation condition. I have also mentioned the high viscosity and low viscosity conditions. At the very end I have proved the discrepancy came due to the high viscosity condition and tried to resolve this using the idea of well known time varying gravitational constant G (t).


Keywords: Fluid mechanics, Quintessence model, cosmological inflation, Viscosity, Gravitational physics
