Extends from PartialHeatTransferLayers.

Information

Overview

Model for heat transfer between buffer storage layers.

Concept

Models conductance of water and buoyancy according to Viskanta et al., 1997. An effective heat conductivity is therefore calculated. Used in BufferStorage model. In addition, the smooth() expression is used for the transition of the buoyancy model.
