Short summary

A planar thermoelectric gas sensor is modeled. By coupling all influences (fluid flow, gas diffusion, heat transfer, chemical reactions, and electrical properties) a model was set up that mirrors the sensor behavior precisely, as the comparison with experimental data shows. The coupling of 3-D and 1-D geometry enables to calculate the temperature distribution, fluid flow, and the gas concentration distribution in the 3-D model, while the chemical reactions are very accurately calculated in 1-D.
