Rock Behaviour near the Tunnel Face

For tunnels it is not only important, how the tunnel and the surrounding rock behave during the life time of the tunnel. It is also very meaningful to understand how the tunnel is behaving, while it is under construction. The basis for this thesis is to understand, how the tunnel behaviour, concerning deformation and stability, is for different...

Modelling the absorption of binary mixtures in plate heat exchangers

Ocean thermal energy conversion (OTEC) is currently developed as a clean and sustainable energy technology for offshore application in tropical areas. The technology shows promising possibilities in combination with the Kalina cycle, a thermodynamic cycle for the generation of energy from low temperature difference heat sources using a working...
