Statistical mechanics of inhomogeneous complex fluids and particle transport models

Statistical mechanics is applied to three systems; Colloid-polymer mixture near a hard wall, irreversible aggregation models, and transport phenomena in engines.

Density Functional theory is used to describe a demixed colloid-polymer mixture at three-phase coexistence. The excess surface free energy for imposed wetting layers are computed and the line tension and the shape of the transition zone are computed via an interface displacement model.

An irreversible aggregation model is introduced with a 'lock-and-key' feature, which shares features of both the Diffusion limited and Reaction limited aggregation models. This is applied to 1d lattices and a square 2d lattice.

The influence of sublinear particle or heat transport in endoreversible engines is invesitgated, with the efficiency at maximum power, the maximum power and these aspects in the linear response regime.
