Numerical investigation of double-flame hot-water boilers under steady-state operation

open access: yesInternational Journal of Thermofluids
This study investigates the optimal arrangement of combustion chambers in double-flame hot-water boilers using computational fluid dynamics (CFD) under steady-state and laminar conditions. The study considers two arrangements: horizontal and vertical. In

Operation-Adaptive Damage Assessment of Steam Turbines Using a Nonlinear Creep-Fatigue Interaction Model

open access: yesIEEE Access, 2020
For sustainable operation, power plants require accurate damage assessment of the steam turbines used for power generation. In the past few decades, steam turbine designs have considered only steady-state operation, without accounting for thermal cyclic ...

Design of 3D equilibria and coils for steady-state operation of tokamaks

open access: yesNuclear Fusion
Inspired by the respective advantages of tokamaks and stellarators, we propose a quasi-axisymmetric (QA) tokamak-stellarator hybrid concept as a steady-state operation mode of standard tokamaks.

Operating tokamaks with steady-state toroidal current [PDF]

open access: yes, 1981
Continuous operation of a tokamak requires, among other things, a means of continuously providing the toroidal current. Various methods have been proposed to provide this current including methods which utilize radio-frequency waves in any of several frequency regimes.
