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
