... gravitational acceleration with fluid depths from 125 to 250 mm were studied. The resulting instability from small acceleration. amplitude random perturbations was recorded and later analyzed As a second stage, non-linearities reduce the growth using high-speed video images. Cavity formation was observed...

Marked rences are noticed between the Nusselt numbers obtained the conjugate and constant temperature analyses. words: conjugate heat transfer, cavity, rotating disk ODUCTION and heat transfer problems encountered in rotor-stator ms such as cavities and enclosures with rotating surfaces of practical...

... 23 05 2008 We present a study of acoustic oscillations induced by an internal airflow over a shallow and a deep cavity. The Kelvin-Helmholtz instability is interacting with an acoustic mode of the duct, leading to a resonance which produces a very high sound level. The influence...
