N2  - The effect of bulk viscosity on the evolution of the spatially flat Friedmann&#8211;Lemaitre&#8211;Robertson&#8211;Walker (FLRW) models in the context of open thermodynamical systems, which allow for particle creation, is analysed within the framework of Brans&#8211;Dicke (BD) theory. The BD field equations are modified with the incorporation of a creation pressure and bulk viscous stress. A class of physically plausible models has been taken into consideration. The behaviour of the particle number density and bulk viscosity is discussed with the evolution of the Brans&#8211;Dicke scalar field.
