Analysis of a new unidimensional model and lateral vibrations of 1-3 piezocomposite side scan sonar array

Author: Shatalov, MY ; Fedotov, I ; Wallis, JR ; Nicolaides, KE Date: Jan 2006 A novel unidimensional model of 1-3 piezocomposite ultrasonic transducers is presented. A new electromechanical model is the generalization of the Smith-Auld unidimentional model, which is formulated in terms of a variational approach. It ... Read more
Excitation of waves in elastic waveguides by piezoelectric patch actuators

Author: Loveday, Philip W Date: Jan 2006 Piezoelectric patch actuators are employed for monitoring the health of structures and for performing active control of vibration. When the structure is long, slender and has constant cross-section, such as a pipe, rail or rod, it can be ... Read more
Experimental and numerical study of near bleed hole heat transfer enhancement in internal turbine blade cooling channels

Author: Scheepers, G ; Morris, RM ; Visser, JA ; Roos, TH ; Snedden, Glen C Date: Jan 2006 This paper describes an experimental and numerical study of the heat transfer augmentation near the entrance to a gas turbine film cooling hole at different engine representative suction ratios (Vhole/V). For the experimental component the ... Read more
Ultrasonic detection of cracks in uniaxial glass fibre rods

Author: Loveday, Philip W ; Wood, D Date: Jan 2006 A non-destructive examination procedure based on a guided wave inspection approach is used for the acoustic examination of glass fibre reinforced composite rods. This paper contains an investigation into the characteristics of guided wave ... Read more
