However, the corrugation
shape used in Zhang's study is triangular, although it was reported that only the pressure drop will be affected by the corrugation
shape and not the heat transfer rate (Kanaris et al.
As shown by further investigations, the more extensive occurrence of constrictions and corrugation
in the ledeburitic steel in comparison with other steels is determined by the thermophysical properties of these materials.
Nevertheless, the pipe invert remained in good condition, reflecting only a few minor "dents" on the leading edge corrugation
It is well known that many factors affect the emergence and development of rail corrugation
; different corrugation
has different mechanisms, and it is difficult to use one method to completely cure rail corrugation
Previous work was conducted by  in order to numerically study the effect of the corrugation
angle and the aspect ratio h / w of the three-dimensional flow and heat transfer in a triangular base channel simulating a corrugated plate heat exchanger.
MS-to-CPS balun section and Fermi-Dirac tapered radiators with corrugation
. Simulation results demonstrate high gain, symmetrical radiation patterns, narrow beamwidth, and low sidelobe levels for whole frequency ranges from 70 to 110 GHz and above.
angles were 30[degrees],60[degrees], and combination of 30[degrees] and 60[degrees].
(2009) used ASHRAE Standard 120 to obtain pressure loss data for one particular corrugation
Standard pipe corrugation
uses a continuous chain of mold blocks mounted on one or two oval tracks to vacuum form a continuously extruded tube or parison.
A permeable 32 casing for working on the twist, the length of the corrugated core is not more than 24 cm, the corrugation
is rigid, colorless 300,000 m, 306,000 byn2.
The application of corrugation
to ordinary structures started with webs on the basis of aeronautic findings in 1924, and it has been used in ordinary steel structures since early 1960s .
The main reasons of unconventionally complicated load-bearing behaviour of such panels are: a complicated geometry that includes the transverse corrugation
, an effect of cold deformation on the materials properties of the panel and, possibly, the complex loads during the service life of the structure.
