Theoretical model: analysing theoretically the air flow through car seat foam material

Popis výsledku v původním jazyce

The publications is focused on analysis of the air flow through car seats. Comfort of car seats is very important property for cars. Air permeability is directly related to the breath ability and comfort of car seats. In this research car seat Poly Urethane (PU) foam with different holes are tested for the air permeability and numerically simulated to predict the flow of air through thick foams. Model of detailed geometry gives good view about detailed flow field (pressure and velocity) in foam volume, influenced by perforations and grooves. But simulated flow is several times different from measured one. The main flow is through perforations (99%) and flow through foam is of two orders lower. Using homogeneous geometry with “averaged” permeability parameters were evaluated from measured values. The coincidence of measured and simulated flow is very good, difference of 1–5%. But it is not possible to get any details of flow in foam volume.
