Abstract:
The aerodynamic effects of wing corrugation on insect flight have received widespread attention. However, there has hardly been any specific focus on dynamic changes to corrugation angle in the models. The flexible vein joints containing resilin in the wings of dragonflies and damselflies enable the longitudinal veins to rotate and thereby change the corrugation angles throughout flapping cycles. Therefore, a two-dimensional corrugated airfoil with time-varying corrugation angles is proposed and the aerodynamic performance is evaluated in terms of aerodynamic force, power and efficiency.

Abstract:
Corrugated steel sections are having a wide variety of applications in engineering fields like civil, mechanical, aviation, etc. The unique properties of corrugated steel sections make them a better option compared to the conventional thin steel sections. In the current study behaviour of thin steel shells with corrugations made of mild steel plates under compression is investigated using finite element software ABAQUS. The corrugated sections and the conventional sections under study are having the same area of cross section. For the corrugated sections, trapezoidal profile was used with corr

Corrugated plate heat exchangers (CPHEs) possess a greater surface area for heat transfer and a heightened level of turbulence as a result of the corrugations. This study presents an experimental analysis comparing the thermal performance of a flat plate heat exchanger and a corrugated plate heat exchanger (CPHE) with varied corrugation angles. The analysis was conducted using water as the test fluid. The comprehensive testing has been carried out on CPHEs with different chevron angles (β) of 30°/30°, 45°/45°, and 60°/60°.

Abstract:
Corrugated Steel Shear Wall (CSSW) is an efficient shear wall system, which has higher energy dissipation capacity, ductility and stiffness when compared to the Steel Plate Shear Wall (SPSW) with flat infill plate. Despite of these advantages, the ultimate load of CSSW is lower than that of SPSW. Various studies conducted to improve the cyclic behavior of CSSW revealed that increasing corrugation angle might enhance energy dissipation capacity and toughness of CSSWs. However, the ultimate load of CSSW was not improved by increasing the corrugation angle. Thus, the current study proposed new co

The Late Cretaceous Orocopia Schist and early Miocene intrusions dominate the mylonitic footwall of the northern Plomosa Mountains.

Coupled surface plasmon as well as waveguide excitations are supported in corrugated photoresist-metal-photoresist geometries. At particular wavelengths, forward and backward propagating excitations are phase matched via the sinusoidal corrugation. This results in second-order Bragg scattering of these excitations into the far-field radiation zone of a sample. Detection of the radiation reveals momentum as well as energy gaps in the dispersion curves of the excitations. These gaps are investigated for different combinations of interacting excitations and for two different detection techniques:

One of the key issues facing rail maintenance crews today is the successful identification and removal of rail corrugations (a sinusoidal, longitudinal rail surface deformation). Typically, rail corrugations are identified through visual inspection (which look for regular surface patterns) or audio methods (which listen for high frequency noise). Once identified, removal is accomplished through rail grinding and consists of running standard “peak-and-plow” grind pattern(s), whereby the corners of the rail are angled upwards to peak the rail, then the top of the rail is ground down (plowed) by
