A new model for damping controlled fluidelastic instability in heat exchanger tube arrays
(2009)Heat exchnager tube arrays are susceptible to damage due to flow-induced vibration, with fluidelastic instability the potnetially the most destructive mechanism. In this paper a simple wake model consisting of a convecting ... -
NEXT GENERATION TACTILE SENSING FOR HUMAN-ROBOT INTERACTION IN INDUSTRIAL ROBOTICS
(2015)Tactile sensing is commonly viewed as one of the basic forms of sensing [24] – intelligent life is rarely found without some capacity for tactile sensing – and it is a fundamental sense in human perception [24, 29]; however ... -
Noise source identification for ducted fan systems
(American Institute of Aeronautics and Astronautics, 2008)Coherence based source analysis techniques can be used to identify the contribution of combustion noise in the exhaust of a jet engine and hence enable the design of noise reduction devices. However, when the combustion noise ... -
