Issues to improve the safety of 18K370 steam turbine operation

E3S Web of Conferences, 2017
The paper presents the process of improving the safety and reliability of operation the 18K370 steam turbines Opole Power Plant since the first failure in 2010 [1], up to install the on-line monitoring system [2].

Sensitivity of the transverse flow towards symmetry energy

, 2011
We study the sensitivity of transverse flow towards symmetry energy in the Fermi energy region as well as at high energies. We find that transverse flow is sensitive to symmetry energy as well as its density dependence in the Fermi energy region. We also

The appeal of the good life: strategies for communicating sufficiency practices and policies

Sustainability: Science, Practice, & Policy
This article examines how sufficiency, an approach to sustainability focused on reducing resource consumption, can be communicated as a pathway to a good life rather than a call to sacrifice. Based on a representative survey in Germany, the findings show

A thermodynamic assessment of working fluids in ORC systems [PDF]

EPJ Web of Conferences, 2019
ORC (Organic Rankine Cycle) is widely used to convert low temperature heat into electricity using organic working fluid. The performance of an ORC installation is influenced deeply by selected working fluid and operation conditions.

Gravitational radiation from dynamical black holes

, 2005
An effective energy tensor for gravitational radiation is identified for uniformly expanding flows of the Hawking mass-energy. It appears in an energy conservation law expressing the change in mass due to the energy densities of matter and gravitational ...

Interplay between Loewner and Dirichlet energies via conformal welding and flow-lines

, 2020
The Loewner energy of a Jordan curve is the Dirichlet energy of its Loewner driving term. It is finite if and only if the curve is a Weil-Petersson quasicircle.

Energy Flow Puzzle of Soliton Ratchets

, 2005
We study the mechanism of directed energy transport for soliton ratchets. The energy flow appears due to the progressive motion of a soliton (kink) which is an energy carrier.

Energy flow observables in hadronic collisions

, 2012
We present recent QCD calculations of energy flow distributions associated with the production of jets at wide rapidity separations in high-energy hadron collisions, and discuss the role of these observables to analyze contributions from parton showering

Energy Dissipation in Fractal-Forced Flow [PDF]

, 2006
The rate of energy dissipation in solutions of the body-forced 3-d incompressible Navier-Stokes equations is rigorously estimated with a focus on its dependence on the nature of the driving force.
