2314 溶液の流体力学における浸透圧について(S42-3 複雑流体の流動現象(3),S42 複雑流体の流動現象)  [in Japanese] 2314 Osmotic Pressure in Fluid Dynamics of Solution  [in Japanese]

Using the method of molecular dynamics, we numerically examine the pressure difference between ideal solution and pure solvent separated by a semi-permeable membrane in the equilibrium state, which is normally termed osmotic pressure. The virial theorem in the system is derived to measure pressures in the ideal solution and the pure solvent, then the validity of van't Hoff law is confirmed up to moderate concentration of the solution.
