(physics)
For any oscillation, the number of vibrations per unit time, multiplied by 2π. Also known as angular velocity; radian frequency.

Angular Frequency

 

the number of complete oscillations made in 2π units of time during a periodic oscillatory process. The relation between the angular frequency ω and the oscillation period Tor the oscillation frequency/is given by the equation ω = 2πf = 2π/T.

angular frequency (ω)

The frequency of a periodic quantity multiplied by 2p; expressed in radians.

To further investigate the complex viscosity [absolute value of [[eta].sup.*]] as function of angular frequency ([omega]), we fitted the experimental complex viscosity data to the Carreau-Yasuda model, as described by the following equation [28]:
For completeness, the numerical angular frequency [[omega].sub.num] derived in this study is plotted against the wavenumber [kappa] in Figs.
The simulation results shown in Fig.4 and Fig.5 verify the ability of the proposed PLL to accurately lock to the supply angular frequency and phase in one ac supply period under line disturbances, such as sag, harmonic, unbalance, whereas the conventional PLL fails to lock accurately in the highly distorted and unbalanced grid.
The guided wave is assumed to be travelling in a waveguide along OZ direction with wavenumber vector [k.sub.z] (direction of which coincides with OZ axis) at angular frequency [omega].
For this purpose, we prepared compatibilized PLA/PCL (90/10) blends irradiated at various doses (5-200 kGy) in the presence of GMA and then measured their complex viscosities in the angular frequency range 0.5-100 rad/s.
The frequency sweep tests were performed at 25[degrees]C over the angular frequency range of 0.1-10 rad/s.
The complex viscosity is shown as a function of angular frequency in figure 5.
in which [v.sub.f](t, x) is the dimensional flow velocity at time t and position x, [V.sub.a] the dimensional mean flow velocity, [V.sub.b] the dimensional amplitude of oscillation velocity, k the wave number and [omega] the angular frequency. The dimensional flow phase velocity can be expressed as [V.sub.[omega]] = [omega]/k.
We write the equations of the BLDCM in the coordinate system d-q, tied to the rotational angular frequency of the rotor.
where [x.sub.h](t) and [x.sub.r](t) denote the body movements of the heartbeat and the respiration signal in the human body, which can be expressed by sinusoids with amplitude a\t and a, and angular frequency [[omega].sub.h] and [[omega].sub.r], respectively.
In asymptotically flat coordinates the angular frequency detected by a distant observer is simply the coordinate angular velocity; that is, one evaluates
