Determining appropriate loss coefficients for use in the nozzle-model of a stage-by-stage turbine model
A previously developed turbine modelling methodology, requiring minimal blade passage information, produced a customizable turbine stage component. This stage-by-stage turbine nozzlemodel component was derived from the synthesis of classical turbine theory and classical nozzle theory enabling the …

Jet Noise Control by Adjoint-Based Optimization
… mixing layer, which serves as near-nozzle model of a jet. The initial-vorticity-thickness Reynolds number is 500, and the free stream Mach numbers are 0.9 and 0.2. Controls are implemented into flow equations as general source terms (body forces, mass sources, and internal energy …

Low load operation of turbine-driven boiler feed pumps
… monitoring. The BFPT system of this Unit was modelled in Flownex, a one-dimensional thermofluid process modelling package. The model included individual pump stages, steam admission valves and a stage-by-stage turbine model utilising custom stage components. These turbine stage components …
