Air Flow Noise Reduction Techniques
Agency / Branch:
DOD / NAVY
The Expeditionary Fighting Vehicle (EFV) currently is extremely noisy. The goal of the proposal is to reduce noise produced by the cooling system for the engine, which consists of fans,heat exchangers, and ducting to the outside. Mezzo is developing mirco tube heat exchangers that provide a much improved ratio of heat transfer/pressure drop compared to conventional heat exchangers (i. e. plate-fin heat exchangers). Mezzo's approach to reducing noise is to replace the heat exchanger currently in use with one that will meet the heat exchanger specifications, while reducing dramatically the pressure drop across the heat exchanger. Reducing the required positive pressure generated by the fan will make it possible to use much quieter fans, as well as fans that require less power. Quieter fans will result in a much quieter system.
