Fluid machines: Expanding the limits, past and future [PDF]

During the 40 yr period from 1940 to 1980, the capabilities and operating limits of fluid machines were greatly extended. This was due to a research program, carried out to meet the needs of aerospace programs. Some of the events are reviewed.

Full annulus simulation on a multistage axial-centrifugal combined compressor

Journal of the Global Power and Propulsion Society
Axial-centrifugal combined compressors are widely used in small and medium aero-engines. This study aims to investigate the performance and flow characteristics of a multistage axial-centrifugal compressor using annulus unsteady simulation. The compressor comprises three axial stages and one radial stage, including the inlet and outlet guide vanes. The

Numerical Simulation of Gas-Liquid Two-Phase Flow in a Downhole Multistage Axial Compressor Under Different Inlet Conditions

Energies
During natural gas field extraction, downhole compressors frequently encounter gas-liquid two-phase flow conditions, yet the internal flow characteristics and performance evolution mechanisms remain insufficiently understood.
