Abstract

Bias acoustic liners have been investigated by a number of researchers and demonstrated to have acoustic benefits. However while research has concentrated on the acoustic aspects of the liner, little research has directly investigated its heat transfer properties. A three dimensional numerical investigation of the fluid flow and heat transfer properties of a single honeycomb cell was carried out in order to develop an understanding of the flow and heat transfer properties of the bias acoustic liner. Experimental measurements of fluid flow and heat transfer properties of an acoustic liner sample were also carried out in order to validate the numerical solution. The experimental results were found to give lower values of heat transfer coefficient at low flow rates when compared with the numerical solution. The numerical solution for pressure loss agreed with Kutscher’s findings. The experimental results agreed with the traditional expression for pressure loss across abrupt expansions.
