A model is developed for double diffusive convection in a bidisperse porous medium. Double diffusive convection is convective movement of fluid due to temperature and salt gradient effects. A bidisperse porous medium is one where there are pores known as macropores, but the solid skeleton contains cracks or fissures which give rise to a porosity in the skeleton, known as microporosity. We concentrate on the case of a single temperature field and attention is focussed on the situation where the layer is heated from below and simultaneously salted from below.
