Abstract:
Methane hydrates are an ice-like substance which is stable only at low temperature and high pressures. At standard conditions they dissociate ("burn") releasing large amounts of (gas) CH4. This effect can be seen simultaneously as an environmental hazard and as an economical opportunity.
In the talk we present a model of evolution of methane hydrates in the undersea sediment and discuss the associated modeling, analysis, and computational challenges. In particular, we discuss adaptivity of the model which allows to compute approximate solutions at low cost.
This is joint work with Marta Torres and Anne Trehu from COAS.
