We consider the following hyperbolic system of PDEs which generalize the classical phase field equations with a non-conserved order parameter φ and temperature u: utt + ε2φtt + γ1ut + ε2γ1φt = αΔu, ε2φtt + γ2ε2φt = ε2Δφ + f(φ) + εu for ε≪1. We present the model, derive a law for the evolution of the interface which generalizes the classical flow by mean curvature equation, and analyze the evolution of some simply shaped interfaces.
