Axisymmetry and azimuthal modes in jet noise

18th AIAA/CEAS Aeroacoustics Conference (33rd AIAA Aeroacoustics Conference), 2012
This paper will show that the matrix of all noise spectra radiated from a jet in a stationary condition, axisymmetric in construction and boundary conditions, has a special invariant structure which simpli es measurements and enables the total composite noise eld to be expressed as a sum of mutually incoherent partial elds.

Incompressibility and axisymmetry: A modified B method

Communications in Numerical Methods in Engineering, 1994
AbstractThe paper deals with a B‐type strain projection method with specific reference to axisymmetric incompressible solids. Essentially the \documentclass{article}\pagestyle{empty}\begin{document}$ \overline{\overline {\rm{B}}} $\end{document} (B double bar) method, which is reported in the present study, is based on Hughes' B‐bar approach utilizing ...

Statistical axisymmetry of the turbulent sphere wake

Experiments in Fluids, 2014
The turbulent sphere wake is studied experimentally at $${Re}=1.9\,10^4$$ using an axisymmetric support that holds the body from upstream. This setup allows the axisymmetry of the mean wake and preserves the

Correcting small magnetic field non-axisymmetries

Nuclear Fusion, 1994
Coil placement errors break the axisymmetry of tokamak magnetic fields. The non-axisymmetries cause magnetic islands, which can enhance locked modes, decrease confinement and lead to disruptions. An algorithm is presented for calculating the currents in small correction coils so that specified islands caused by known magnetic field errors will be ...

Transmission Line Modelling of Axisymmetry Curvilinear Structures

IET Colloquium on Antennas, Wireless and Electromagnetics 2014, 2014
The requirement for accurate and efficient antenna design process is becoming more important with the advancement in technology and raised standards for electromagnetic compatibility. The accurate numerical solution of problems in electromagnetics ideally requires conformity of the mesh with the structure being modelled in order to attain this level of

Constraining the Milky Way non-axisymmetries with Gaia

Proceedings of the International Astronomical Union, 2019
AbstractThe unprecedented amount and accuracy of kinematic data from the second release of the Gaia mission have started revolutionizing our understanding of the dynamics of the Milky Way disk. The detailed stellar velocity field in the Galactic disk should allow us to constrain with unprecedented precision the parameters of the non-axisymmetric modes ...

Stationary axisymmetry electromagnetic fields in the Kerr metric

Journal of Physics A: Mathematical and General, 1979
A procedure for calculating the Debye potential corresponding to a stationary axisymmetric distribution of charges and currents in the Kerr metric is given. The electromagnetic potential is derived by differentiation. The potential of a point charge on the symmetry axis and the value of the charge resulting from the accretion in the case of a charged ...
