The research area “Thermodynamics” deals with thermodynamic questions of selected mechanical engineering topics.

The field of activities includes the analysis of energetic and thermodynamic processes of reciprocating compressors and cooling cycles for domestic refrigeration or cycles for automotive waste heat recovery. This is carried out by simulation and measurement of heat balances, flow phenomena as well as heat and mass transfer using also proprietary software. Particular attention is paid to transient phenomena.

Another research area focuses on the thermal behavior and the thermal management of engines and vehicles. In this field research projects are conducted dealing for example with the modeling of the cooling circuit of internal combustion engines. Raimund Almbauer supports projects of the K2-Research Centre “Mobility” as a key researcher.
