Experiments on turbulent structure and heat transfer in a two-dimensional jet

Turbulence and heat transfer were measured in a heated jet of air and development of self-similarity was determined. Temperature fluctuation balance was measured across the jet. Turbulent velocity and temperature spectra and their dependence on jet Reynolds number and location across the jet were measured. The jet nozzles with length to width ratios of 20, 40, and 140 were used and the effect of aspect ratio on turbulent structure was determined.
