Unsteady lifting line theory using the Wagner function
A method is presented to model the incompressible, attached, unsteady lift and moment acting on a thin three-dimensional wing in the time domain. The model is based on the combination of Wagner theory and lifting line theory trough the unsteady Kutta ...

Numerical study of nonlinearity of unsteady aerodynamics for NLR7301 profile [PDF]
Details of unsteady aerodynamics for a two dimensional NLR7301 airfoil with flap were numerically investigated by a Navier-Stokes code in the transonic regime. Unsteady aerodynamic coefficients such as lift and pitching moment show nonlinear aspects in a

The Effects of Unsteady On-Road Flow Conditions on Cabin Noise [PDF]
On-road, a vehicle experiences unsteady flow conditions due to turbulence in the natural wind, moving through the unsteady wakes of other road vehicles and travelling through the stationary wakes generated by roadside obstacles.

Asymptotic Expansion of the Kernel Function in Subsonic Unsteady Lifting Surface Theory
A computer oriented asymptotic expansion of a singular integral function is presented. The function dealt with appears in the kemel of the integral equation which is solved for pressure distributions of subsonic unsteady lifting surfaces. Values of the function can be accurately computed in a short time by using the present expansion.

Three dimensional frequency-domain solution method for unsteady turbomachinery flows [PDF]
The three-dimensional calculation of unsteady flows is increasingly gaining importance in the prediction of turbomachinery flow problems. A three-dimensional Euler/Navier-Stokes solver incorporating the time-linearized method and the nonlinear harmonic ...
