Modelling of a steam network using data reconciliation as a management tool

Laurent Gabriel Félix Alexandre Stéphane Bungener

The first step towards managing and optimising the steam network of an industrial cluster or plant is to accurately measure the production and consumption of the different levels of steam. Measurement errors as well as unmeasured contributors lead to inacc ...

Numerical and Experimental Investigation of the Aerodynamic Excitation of a Model Low-Pressure Steam Turbine Stage Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

The diversification of power generation methods within existing power networks has increased the requirement for operational flexibility of plants employing steam turbines. This has led to the situation where steam turbines may operate at very low volume f ...

Non-synchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to r ...

In this thesis, we develop a new large-eddy simulation (LES) framework to simulate atmospheric boundary layer (ABL) flows through wind turbines and wind farms. A Lagrangian scale-dependent dynamic model is used to compute the Smagorinsky model coefficient ...

Procédé et dispositif de fabrication de briquettes

Process for producing a briquette containing carbon carriers (2): mixing the carbon carriers (2) together with a binder system (3) with introduction of steam and the mixture obtained is pressed to form briquettes. At least one of drying carbon carriers (2) ...

Experimental Aeroelastic Investigation of Vibrating Turbine Blade Clusters

Peter Ott, Achim Zanker

The presented work consists of the presentation and discussion of unsteady experimental results of controlled vibration measurements for two single-blade and two cluster test cases subjected to the same subsonic flow conditions. The experiments were perfor ...
