title = "Turbulence produced by injection of heated jets",
abstract = "An experimental study of velocity and thermal turbulence generation is presented. These studies are directed to simple and compact laboratory simulation of atmospheric turbulence. The velocity and temperature turbulence was produced by injection of heated air into a main uniform flow of air. The turbulence velocity and temperature flow field was mapped and the one dimensional energy spectra and integral scales were measured. Homogeneous and isotropic turbulence with 18.5\% streamwise velocity fluctuation intensity was achieved 8 mesh sizes downstream of the injector. At this location the turbulence was homogeneous within 5\% and the ratio between the longitudinal and the perpendicular fluctuation components was 1.26. The average integral scale of the streamwise velocity turbulence was 18 mm, 0.18 units of mesh size, and the ratio between the velocity and temperature integral scales was 1.04. The high yet nearly homogeneous turbulence achieved for X/M between 6 and 8 downstream of the injector is well suited to atmospheric turbulence simulation studies.",
