Results are presented from a cold-flow investigation of acoustic responses driven by flow through two annular baffles in a cylindrical cavity, having (approximately) closed-closed end conditions. The interaction of the flow with cavity acoustic reson

The acoustic boundary-layer structure is investigated in a cylindrical tube where steady sidewall injection is imposed upon an oscillatory e ow. Culick’ s steady, rotational, and inviscid solution is assumed for the mean e ow. The time-dependent ve

A theoretical and experimental approach was used to investigate the motion and effectiveness of a Self-Compensating Dynamic Balancer (SCDB). This is a device intended to minimize the effects of rotor imbalance and vibratory forces on a rotating syste

Heat transfer in an oscillating flow at high acoustic Reynolds number has been investigated using the mass-transfer analogy. Subliming naphthalene has been used in the experiments. In these experiments the acoustic Reynolds number was varied over a r

In this work, the onset of turbulence inside a rectangular chamber is investigated, with and without side-wall injection, in the presence of an oscillatory pressure gradient. Three techniques are used to define the transition from laminar to turbulen
