FLOW DISTRIBUTION STUDY FOR A ROTARY REGENERATOR.
Abstract
The study provides an evaluation by means of analysis and experimentation for achieving proper flow distribution to highly compact surface densities - densities in excess of 2000 sq. ft/cu. ft. Heat transfer matrix analyses were performed to give an indication of the face area requirements and flow lengths for representative rotary regenerator applications. Aerodynamic analyses were conducted to establish the optimum ratio between hot and cold gas rotary regenerator frontal areas. Aerodynamic analyses were performed to derive preliminary contoured shape configurations to give uniform distribution through the selected matrices. These analyses provided preliminary concepts for an experimental program. Definition of an experimental program included design and fabrication of all necessary experimental laboratory hardware, heat transfer matrices and the necessary flow directing devices along with proper implementation of required instrumentation. The experimental air flow runs were conducted using plain screen matrices, i.e. matrices without flow directing devices, which had air face to air frontal area ratios as follows: 1: 1, 3:1, 6:1, and 9:1. Each run provided experimental data for three or more different air flow rates. Further experimental air flow runs were conducted using above cited matrices in conjunction with 25 different vane configurations. Again each run provided data for 3 or more different air flow rates. A computer program was established to reduce experimental data and to plot curves. (Author)
