Intraperitoneal therapies such as peritoneal dialysis or regional chemotherapy use large volumes of solution within the peritoneal cavity. These volumes increase intraperitoneal hydrostatic pressure (P(ip)), which causes flow of the solution into tissues that surround the cavity. The goal of this paper is to integrate new experimental findings in a rigorous mathematical model to predict protein...

The nonlinear corrections for a Helmholtz resonator type impedance based on systematic asymptotic solution of the pertaining equations has been formulated in [1]. The length of the cavity considered was much smaller compared to the typical acoustic wavelength of interest so that the pressure inside could be assumed to be uniform. This way, the cavity worked as a spring to the external excitatio...

In the last decades, Synthetic jet actuators have gained much interest among the flow control techniques due to their short response time, high jet velocity and absence of traditional piping, which matches the requirements of reduced size and low weight. A synthetic jet is generated by the diaphragm oscillation (generally driven by a piezoelectric element) in a relatively small cavity, producin...

This paper investigates the interaction between the shear layer over a circular cavity and the flowexcited acoustic response of the volume to shear layer instability modes. Within the fluid-resonant category of cavity oscillation, most research has been carried out on rectangular geometries and where cylinders are considered, side branch and Helmholtz oscillators are most common. In these studi...

We report on experimental observation of radiation-pressure induced effects in a highpower optical cavity. These effects play an important role in next generation gravitational wave detectors, as well as quantum non-demolition devices. We describe two experiments in which a low-transmission input mirror and near-perfectly-reflective end mirror are suspended as pendulums. A unified model of opto...

[1] We present results from Lyon-Fedder-Mobarry (LFM) global, three-dimensional magnetohydrodynamic (MHD) simulations of the solar wind-magnetosphere interaction. We use these simulations to investigate the role that solar wind dynamic pressure fluctuations play in the generation of magnetospheric ultra-low frequency (ULF) pulsations. The simulations presented in this study are driven with idea...

The inherent attenuation of a homogeneous viscous medium limits radiation propagation, thereby restricting the use of many high-frequency acoustic devices to only short-range applications. Here, we design and experimentally demonstrate an acoustic metamaterial localization cavity which is used for sound pressure level (SPL) gain using double coiled up space like structures thereby increasing th...

'I A cavity pressure method for measuring t he gain of hearing aids has been--developed. It has the advantage of req uiring no " dead " room, allo~ing a compact setup. The method has been investigated as to its validity and t he degree to which diffraction effects are avoided. Comparisons with free-field data are made. The applicability of results obtained by this method to t he specifi cation ...

This work is concerned with application of the Lattice Boltzmznn Method (LBM) to compute flows in micro-geometries. The choice of using LBM for microflow simulation is a good one owing to the fact that it is based on the Boltzmann equation which is valid for the whole range of the Knudsen number. In this work LBM is applied to simulate the pressure driven microchannel flows and micro lid-driven...

Optical fiber based Extrinsic Fabry-Perot Interferometric (EFPI) sensor significantly emerged as an advanced optical sensor for the health monitoring of civil, mechanical and aeronautical structures. This sensor responds its well capability also towards the measurement of acoustic/shock wave pressure. This paper presents an approach for high blast (acoustic/shock wave) pressure measurement usin...
