Experimental study on sunlight absorption characteristics of Au-CuS blended nanofluids

This report deals with a theoretical and experimental study of the low frequency sound absorption characteristics of perforated honeycomb sandwich panels. The derivations of formulae for absorption in terms of double perforation ratio and air gap are presented. Results show that the honeycomb absorber, with double perforated sheets, can be an effective low frequency absorber for frequencies down to 63 Hz. In addition, honeycomb panels have advantages over other low frequency absorbers in that they are light weight and strong.

Absorption Characteristics

Thin-walled tubes are widely used as energy absorbers in various vehicles and moving parts. The objective of this study is to investigate the energy absorption characteristics of tubes with corrugations in different geometries, under lateral loading. In order to produce corrugations, an innovative solution is introduced. Quasi-static tests were conducted to study the effect of changing the corrugation geometry (type and amplitude). The results show that tubes with corrugations have a higher mean crushing force which is directly proportional to the number of corrugations and their amplitudes. Moreover, it was observed that corrugated tubes can absorb approximately four times more energy than the tubes without corrugations in the same sizes and weights. Finally, it was found that corrugated tubes are more effective in lateral direction as energy absorbers, as they present suitable force–deflection responses.

Absorption Characteristics

From the previous researches, the author of this paper finds that the steel tube with the hexagonal section under the lateral compression has a good energy absorption property. In order to further enhance the energy absorption of the steel tube with the hexagonal section, this paper develops the polyurethane foam filled hexagonal steel tube, and through experiment, studies its characteristics of lateral compression energy absorption, and makes the comparative analysis against the hollow hexagonal steel tube. The results show that the hexagonal section steel tube filled with polyurethane foam has substantially growth in both the loads of the yield platform and the energy absorption capability.
