The ESA project MELiSSA is an artificial ecosystem of micro-organisms and higher plants with the aim of enabling human survival in space by providing for generation of food, water recycling, atmospheric regeneration, and waste management. Essential for the use of an artificial ecosystem as a reliable life support system is that it has to be fully predictable. To enable the understanding and predictability of the higher plant compartment of MELiSSA, the major goal of the Food Characterisation project is to fully understand the chosen plants and all the processes related to them. To fulfill that purpose mathematical models describing those processes have to be elaborated. One important process to model is the mass flux at the surface of the plant leaf.
The aim of this report is to state the equations describing the various diffusion processes at the surface of plant leaves. This includes and focuses on the release of water vapour and the release and uptake of carbon dioxide and oxygen. The result of the project, i.e. the model presented in this report, is to be used in an extended model which will describe all the processes involving the plant and its interaction with the surrounding environment.
