Sound propagation in slowly varying lined flow ducts of arbitrary cross section
Sound transmission through ducts of constant cross section with a uniform inviscid mean flow and a constant acoustic lining (impedance wall) is classically described by a modal expansion, where the modes are eigenfunctions of the corresponding Laplace eigenvalue problem along a duct cross section. A natural extension for ducts with cross section and wall impedance that are varying slowly (compa...
متن کاملPULSATILE MOTION OF BLOOD IN A CIRCULAR TUBE OF VARYING CROSS-SECTION WITH SLIP FLOW
Pulsatile motion of blood in a circular tube of varying cross-section has been developed by considering slip flow at the tube wall and the blood to be a non- Newtonian biviscous incompressible fluid. The tube wall is supposed to be permeable and the fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the tube wall. The tangential velocity of the fl...
متن کاملLocal Orthogonal Mappings and Operator Formulation for Varying Cross-sectional Ducts
A method is developed for solving the two dimensional Helmholtz equation in a duct with varying cross-section region bounded by a curved top and flat bottom, having one region inside. To compute the propagation of sound waves in a curved duct with a curved internal interface is difficult problem. One method is to transform the wave equation into a solvable form and making the curved interface p...
متن کاملDominance in hands and cross-sectional area of median nerve in carpal tunnel syndrome
Introduction: Currently, neuroresearchers report that the median nerve shows severity-correlated intracarpal enlargement in idiopathic carpal tunnel syndrome (CTS) as a most common peripheral neuropathic disorder. The purpose of this paper was to investigate ultrasonography morphological findings in patients with idiopathic CTS and comparing some physical properties such as age, gender, BMI wit...
متن کاملCross-Sectional Relative Price Variability and Inflation in Turkey: Time Varying Estimation
Abstract This study investigates the empirical validity of the variability hypothesis in Turkey for the period of February 2005-November 2015, by using cross-sectional relative price data and by focusing on the assumptions of linearity and stability. The linearity assumption between the two variables is ensured by estimating quadratic regression equation. The assumption of stability is secur...
