Simulationen weisen der Luft den Weg - die intelligente Stalllüftung

Ventilation companies are asked by farmers to arrange the stable so that the target number of animals can be housed. The companies take the DIN 18910 as orientation. Therewith the amount of air is known to be moved through the stable in order to transport the thermal and harmful loads from inside to outside. The guidance of air is regulated not in particular. Tabulation libraries gives guide values for e.g. air jet behaviour etc. Experiences grasp. Within companies the learning by mistakes help to try to avoid the same error when working for the next farmer. That there is a forsighted way to get knowledge about the fluid flow behaviour by numerical simulation is neglected by nearly all ventilation companies. At every stable design the customer, that is the farmer, should be told what he can expect. Here computational simulation might lead to a solution. This way will develop into the state of technology in the future. In the following an air guiding constellation for a fattening pig compartment is described, that reduces the emission from the stable and enhances the animal behaviour persistently.
