Mathematical model of the thermal regeneration of a wall ...

A mathematical model of the regeneration is formulated as a system of nonlinear partial differential equations describing the conservation of mass, momentum and energy. Numerical solutions are obtained by using a combination of finite element and finite difference techniques for the spatial discretization and using an implicit ordinary differential equation solver for the resulting time integration.
