Aero-, thermodynamics, fluid dynamics and environmental physics

Major parts of modern, high-speed rail links are often built as tunnels. Because of the elevated train velocities, various aerodynamic phenomena occurring during train passage need to be considered for tunnel design. Additionally in long tunnels and in metro systems the tunnel climate might be an important issue for the tunnel design.

Interactions with the environment are to be taken into account when designing and constructing underground infrastructure buildings. HBI Haerter realizes the relevant parameters and analyses the environmental effects on underground plants with regard to the construction and operation phase. Conversely, HBI analyses the effects of infrastructure buildings on the environment and plans appropriate measures. Relevant environmental-physical services by HBI concern analyses, planning of measures, measurements and simulations.
