Boss forming, which is sometimes called hub forming, has attracted its attention as an environment-friendly rotary forming process to form a circular plate with a hole into a boss shape. An experimental study was conducted to survey the technological possibility of boss forming. Boss forming of A1050-O commercially pure aluminum plate of 10 mm thickness was carried out at room temperature under various working conditions. The effects of the working conditions on the metal flow in boss forming were clarified experimentally.

Thermoacoustic Refrigeration

Abstract Thermoacoustic Refrigeration is a phenomenon in which cooling takes place by using high-intensity sound waves, which is gathering attention of many researchers in recent days. This alternative environment friendly technology could play an important role in near future. The paper is mainly an experimental case study on a thermoacoustic refrigeration system build in a laboratory environment with the commonly available materials. The setup was tested for various frequencies of sound to observe its effect on the drop of temperature. The refrigeration effect was also studied for various stack materials. It was observed that sinusoidal waves are better responsive to the production of the refrigeration effect. Moreover, the effect is more pronounced for paper-foil made stack.
