  In this paper, we consider two-component dark energy models in Lyra manifold.
The first component is assumed as a quintessence field while the second model
may be a viscous polytropic gas, a viscous Van der Waals gas or a viscous
modified Chaplygin gas. We also consider the possibility of interaction between
components. By using numerical analysis, we study some cosmological parameters
of the models and compare them with observational data.
