Sentence examples for duct section from inspiring English sources
Two marine applications are examined using the model: (a) a scavenge air cooler, and (b) an auxiliary engine exhaust gas duct section integrated with thermoelectric generators.
To achieve these objectives, the scattering matrix of the lined duct section is obtained experimentally for two specific muffler configurations operating in multimodal propagation conditions.
The resulting eigenvalue calculation shows good agreement with a well-tested one-dimensional solver when applied to a circular duct section with constant impedance.
The basic assumption of the theory is that the effects of refraction and wall compliance on the fundamental mode remain within ranges in which the acoustic fluctuations are essentially uniform over a duct section.
The background of the present paper is the performance of lined conical duct sections in silencers.
The method is also used to investigate acoustic wave propagation through parabolically curved, circular duct sections.
In the present paper, the wedge is subdivided into duct sections with parallel walls (the boundary is stepped); the fields in the sections are composed of duct modes (modes in a straight lined duct); the mode amplitudes are determined from the boundary conditions at the section limits.
An advantage of the vector-based mapping strategy proposed is that attributes such as histological descriptions and results of molecular or immuno-histochemical analysis can be encoded and associated with the relevant vector objects (e.g., duct sections, lobules) in the three-dimensional breast parenchyma map for analysis and visualisation as appropriate.
At a helium gas temperature over 700 °C, the cumulative operation time for the duct test section reached 350 h.
With helium gas at pressure of about 3.0 MPa and a temperature over 900 °C, the continuous operation time for the duct test section lasted 98 h.
A full-scale duct test section was then made according to the design parameters, and its thermal performance experiment was carried out in a helium test loop.
