Experimental results from single-pipe diffusers for stratified thermal energy storage.

Author(s) : WILDIN M. W.

Summary

Current practice in stratified storage of thermal energy for cooling often uses diffusers in the form of single pipes with distributed openings. This investigation was undertaken in an effort to identify diffuser parameter values that minimize mixing during and immediately after thermocline formation, thus tending to optimize the performance of stratified tanks that use such diffusers. To achieve the objective, data were obtained on the temperature distributions produced by charging a rectangular scale-model tank with chilled water using several different diffusers. Use a large number of more closely spaced openings tended to improve diffuser performance.
