Solvation change induced by a chemical reaction can move a macromolecule in a specific direction. The hydrodynamic effect on a solvation motor was studied by using molecular dynamics simulations with a simple model. We examined the dependence of motor displacement induced by the chemical reaction on the size of the basic cell. The size dependence given by the simulation sat on a straight line as a function of the system size, and the displacement in an infinite system was estimated from the plot.
