Optimal regularity for phase transition problems with convection
Annales de l'I.H.P. Analyse non linéaire, Tome 32 (2015) no. 4, pp. 715-740.

In this paper we consider a steady state phase transition problem with given convection v. We prove, among other things, that the weak solution is locally Lipschitz continuous provided that 𝐯=Dξ and ξ is a harmonic function. Moreover, for continuous casting problem, i.e. when v is constant vector, we show that Lipschitz free boundaries are C 1 regular surfaces.
