Numerical Investigations of Unsteady Flow in a Centrifugal Pump with a Vaned Diffuser
, 2013 Computational fluid dynamics (CFD) analyses were made to study the unsteady three-dimensional turbulence in the ERCOFTAC centrifugal pump test case. The simulations were carried out using the OpenFOAM Open Source CFD software.

Experimental and Numerical Investigation of Unforced unsteadiness in a Vaneless Radial Diffuser [PDF]
, 2011 The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle Image Velocimetry (PIV) recording

Numerical Simulation of Folding Tail Aeroelasticity Based on the CFD/CSD Coupling Method
VibrationThis paper presents a CFD/CSD coupling method for aeroelastic simulation of folding tail morphing aircraft. The unsteady aerodynamic analysis is based on an in-house computational fluid dynamics (CFD) solver for the Euler equations, and emphasis is made ...

Unsteady transonic viscous-inviscid interaction using Euler and boundary-layer equations [PDF]
The Euler code is used extensively for computation of transonic unsteady aerodynamics. The boundary layer code solves the 3-D, compressible, unsteady, mean flow kinetic energy integral boundary layer equations in the direct mode.

Unsteady stagnation-point heat transfer during passage of a concentrated vortex [PDF]
The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent ...

Supersonic axial-flow fan flutter [PDF]
Lane's (1957) analytical formulation of the unsteady pressure distribution on an oscillating two-dimensional flat plate cascade in supersonic axial flow has been developed into a computer code. This unsteady aerodynamic code has shown good agreement with

Study of Convective Flow Effects in Endwall Casing Treatments in Transonic Compressor Rotors [PDF]
, 2012 The unsteady convective flow effects in a transonic compressor rotor with a circumferential-groove casing treatment are investigated in this paper. Experimental results show that the circumferential-groove casing treatment increases the compressor stall ...
