Analysis and mitigation of numerical dissipation in inviscid and viscid computation of vortex-dominated flows [PDF]

open access: yes
The conservative unsteady Euler equations for the flow relative motion in the moving frame of reference are used to solve for the steady and unsteady flows around sharp-edged delta wings.

Compressibility effects in the Kemp-Sears Problem [PDF]

open access: yes
The effects of including compressibility in the Kemp-Sears problem of aerodynamic interference between moving blade rows are examined. Methods of linearized, subsonic, plane, unsteady flow are adopted.

Analysis of two-dimensional incompressible flow past airfoils using unsteady Navier-Stokes equations [PDF]

open access: yes
The conservative form of the unsteady Navier-Stokes equations in terms of vorticity and stream function in generalized curvilinear coordinates are used to analyze the flow structure of steady separation and unsteady flow with massive separation.

Unsteady Flow Phenomena in Centrifugal Fans : 2nd Report, Three-Dimensional Unsteady Flow Measurement

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1980
A new method of measuring a three dimensional unsteady flow is presented in this paper. The method was applied to the measurement of a flow just before the impeller of a centrifugal fan operating in the state of rotating stall, and complex flow patterns in that place were made clear.

A numerical study of the 2- and 3-dimensional unsteady Navier-Stokes equations in velocity-vorticity variables using compact difference schemes [PDF]

open access: yes
A compact finite-difference approximation to the unsteady Navier-Stokes equations in velocity-vorticity variables is used to numerically simulate a number of flows. These include two-dimensional laminar flow of a vortex evolving over a flat plate with an

Numerical studies of unsteady transonic flow over an oscillating airfoil [PDF]

open access: yes
A finite-difference solution to the Navier-Stokes equations combined with a time-varying grid-generation technique was used to compute unsteady transonic flow over an oscillating airfoil.
