Transient coarsening behaviour in the CahnHilliard model.
Acta Materialia, 51(10):28232830, 2003. [ bib  .pdf 1 ] We study twodimensional coarsening by simulations for the CahnHilliard model. A scale invariance of the sharp interface limit of this model suggests that the characteristic length scale grows proportional to t^1/3, respectively the energy density decreases as t^1/3. We compare the coarsening dynamics for different choices of data for different volume fractions. We observe that, depending on the specific data, the coarsening process can over a large time window be much slower than expected by dimensional analysis.
