Thermodynamic Models

  • Gunnar Stiesch
Part of the Heat and Mass Transfer book series (HMT)


The models described in this chapter are called thermodynamic models since they are based on the first law of thermodynamics and mass balances only. The principles of momentum conservation are not considered in this model type and spatial variations of composition and thermodynamic properties are neglected. Thus, the entire combustion chamber of an internal combustion engine is typically treated as a single, homogeneously mixed zone. These assumptions obviously represent a significant abstraction of the problem and prohibit the usage of thermodynamic models in order to study locally resolved subprocesses such as detailed spray processes or reaction chemistry. However, the great advantage of these models is that they are both easy to handle and computationally very efficient. Therefore, they are still widely used in applications where there is only interest in spatially and sometimes even temporally averaged information and where computational time is crucial.
