The natural vibration characteristics of human ossicles.

BACKGROUND Recently, a model of the ossicular chain for finite element analysis has been developed. However, the natural vibration characteristics of human ossicles have never been studied. Herein, we investigated the dynamic characteristics of the coupling of in-vivo ossicles using finite element analysis. METHODS The geometry of the ossicular chain was obtained by high-resolution computed t...

Vibration analysis of double bonded composite pipe reinforced by BNNTs conveying oil

In the present research, nonlinear vibration in a coupled system of Boron-Nitride nano-tube reinforced composite (BNNTRC) oil pipes is studied. Single-walled Boron-Nitride nano-tubes (SWBNNTs) are arranged in a longitudinal direction inside Poly-vinylidene fluoride (PVDF) matrix. Damping and shearing effects of surrounded medium are taken into account by visco-Pasternak model. Based on piezoele...

Impedance of a Long Slot in a Coaxial Beam Pipe*

We derive an analytical expression for the coupling impedance and loss factor of a long narrow slot in a coaxial beam pipe. The method used differs from the classical Bethe’s theory of diffraction since we define differential polarizabilities to take into account the effect of the interference between the fields scattered all along the slot. The expressions obtained are thus valid even for slot...

The Overall Heat Transfer Characteristics of a Double Pipe Heat Exchanger: Comparison of Experimental Data with Predictions of Standard Correlations

The single-phase flow and thermal performance of a double pipe heat exchanger are examined by experimental methods. The working fluid is water at atmospheric pressure. Temperature measurements at the inlet and outlet of the two streams and also at an intermediate point half way between the inlet and outlet is made, using copper-constantan thermocouple wires. Mass flow rates for each stream are ...
