Abstract

The project to study the turbulent diffusion flame, by the Department of Chemical Engineering of the California Institute of Technology, is quite comprehensive. Only a small portion of the project was included in the scope of this thesis. A study will be made of the turbulent diffusion flame that is formed when fuel gas is introduced, through the end of a 1-inch-diameter tube, into air, flowing in a 4-inch-diameter tube, and combustion is started. The plan of investigation is divided into two parts. First, a study will be made of the mixing zone when combustion is not occurring; and secondly, a study will be made of the combustion zone when combustion is taking place. The work accomplished in the scope of this thesis was the design and assistance in the fabrication and assembly of the equipment necessary to conduct this investigation. This was completed with the exception of the sampler to be used in obtaining samples of the burning gases. In addition, one series of tests was made at one stream velocity. The equipment functioned very well during the series of runs. Recommendations for a few minor changes are included in this report. The incorporation of these changes should increase slightly both the speed of taking data and the accuracy of the results. The results obtained in the series of tests indicated that the desired data can be obtained with this equipment.
