The phrase "duct shape" is a correct and usable part of a sentence in written English.
It refers to the physical form or structure of a duct, which is a tube or channel that carries fluids. Example sentence: The air conditioning system was malfunctioning due to the irregular duct shape, causing uneven cooling in different areas of the building.
It is found that even with restriction to the simplest fluid, very different mathematical techniques are needed for a simple change in duct shape.
An approximate relationship is developed which is very nearly a universal solution for any duct shape in terms of the Bejan number and duct aspect ratio.
A boundary element method is used to incorporate the duct shape which is represented by a series of panels with constant distributions of sources and doublets.
This means that the developed ADS by rectangular duct shape and three meter duct width can transfer daylight as deep as 12.5 m and 20 m from window wall in overcast and intermediate sky conditions respectively.
A thermal vapor compressor (TVC) in which the subsonic/supersonic flow appears simultaneously, has been accurately designed through the CFD analysis for the various shape parameters such as the primary nozzle shape, converging duct shape, mixing tube diameter, and so on.
The duct shape is commonly that of incompletely formed glands.
Performance characteristics and velocity field of a 16 inch diameter ducted propeller are investigated experimentally using five different duct shapes.
Subsequently, the ADS simulation involves different variables of duct shapes, duct width, duct length and distributor configuration in an open plan office.
The current study seeks to determine the Anidolic Daylighting System (ADS) variables that are applicable under tropical climate, according to modified duct shapes, duct width, duct length and distributor configuration.
It is shown that elementary exact solutions of the Webster equation exist only (section 3.1) for these seven shapes: namely, the exponential, catenoidal, sinusoidal and inverse ducts; it is implied that for all other duct shapes the exact acoustic fields involve special functions, in infinite or finite terms, e.g., Bessel and Hermite functions respectively for power-law and Gaussian horns.
Boeing, for example, might use the technique to make and test air-duct shapes before committing to a final design.
