  Aqueous foams coarsen with time due to gas diffusion through the liquid. The
mean bubble size grows, and small bubbles vanish. However, coarsening is little
understood for foams with an intermediate liquid content, particularly in the
presence of surfactant-induced attractive forces between the bubbles, measured
by the contact angle. Rigorous bubble growth laws have yet to be developed, and
the evolution of bulk foam properties is unclear. We present a quasi-static
numerical model for coarsening in two-dimensional wet foams, focusing on growth
laws and related bubble properties. The deformation of bubbles is modelled
using a finite-element approach, and the gas flow through both films and
Plateau borders is approximated. We give results for disordered two-dimensional
wet foams with 256 to 1024 bubbles, at liquid fractions from $2\%$ to beyond
the zero-contact-angle jamming transition, and with contact angles up to
$10^\circ$. Simple analytical models are developed to aid interpretation. We
find that nonzero contact angle causes a proxy of the initial coarsening rate
to plateau at large liquid fractions, and that the individual bubble growth
rates are closely related to their effective number of neighbours.
