The structure of a non-isothermal jet coming into a single cell, or room of actual scale, has been studied, as well as the exchange of turbulent heat related to the jet. Using a data base of velocity by sonic and hot-wire anemometers and temperature measured by thermocouple, they are calculated several characteristic parameters of the flow: the non-dimensional numbers Archimedes (Ar), Rayleig (Ra) and Nusselt (Nu) and the thermal wide of the flow. The intensity of turbulence and the momentum and heat fluxes have been obtained by means of an analysis of variance in order to test the dependence among these parameters, all performed under statistical criteria. Results show the behaviour of the strength of thermal origin and from inertia associated to the jet and the turbulent transport of heat into the cell. [ABSTRACT FROM AUTHOR]
