摘要:Abstract(#br)A pseudo-spectral method based on Fourier expansions in a Cartesian coordinate system is shown to be an economical method for direct numerical simulation studies of transitional round jets. Several characteristics of the solutions are presented to establish the valid...

摘要:Abstract(#br)The evolution of a reacting, circular mixing layer - a model of round-jet flow - in its transition to turbulence was studied by direct numerical simulation. An economical Fourier pseudospectral method was combined with the third-order Adams-Bashforth scheme to integr...

摘要:AbstractThe evolution to turbulence of a thin circular mixing-layer (jet-like flow) was computed using a Fourier-spectral, 4th-order predictor-corrector scheme. Data for Reynolds number (based on initial jet-diameter and velocity difference across shear layer) of 1600 on a 643 gr...
