v7.31.131 WTNV131 - Diffusion of air dissolved in water (3D)

Summary:

Here we consider a problem with constant temperature and saturation. By appropriate boundary conditions, constant water pressure and vapor pressure are imposed. A gas pressure is imposed on one edge of the domain (zero flow on the other side). Only the pressures of dry air and dissolved air connected by Henry’s law change. This problem comes down to an equation for dry air pressure such as a « heat equation ». The reference solution will then be a thermal calculation ASTER. This test case is extension \(\mathrm{3D}\) of test case WTNP103.
