Effect of Quench-Ageing on Microstructural Evolution and Damping Behaviour of Zn-27Al-1Cu Alloy
(ISLAC’18 “1st International Symposium on Light Alloys and Composite Materials", 2018-03-22)
A ternary Zn-27Al-1Cu alloy was prepared by permanent mould casting. The microstructural evolution and damping behaviour of the Zn-27Al-1Cu alloy were investigated in different periods of ageing after subjected to solution ...
Optimum Tuning of a Gyroscopic Vibration Absorber for Vibration Control of a Vertical Cantilever Beam with Tip Mass
(Int Inst Acoustics & Vibration, 2019)
In this paper, a symmetric gyro with coupling to the tip mass of a beam mounted on a vibrating base is considered. Taking advantage of the angular momentum of the rotating gyroscope, gyrostabilizer systems are expected to ...
Exergetic Evaluation of Speed and Load Effects in Spark Ignition Engines
(Edp Sciences S A, 2012)
Exergetic Evaluation of Speed and Load Effects in Spark Ignition Engines This study investigates the effects of various operating conditions in spark ignition engines via an exergy analysis. A thermodynamic cycle model ...
Optimization insulation thickness and reduction of CO2 emissions for pipes in all generation district heating networks
(SAGE PUBLICATIONS LTD, 2022)
District heating systems are provided solutions for the increasing energy problems in high-population cities. Energy costs go up depending on increasing heat loss in DHS's distribution network. Heat loss from the network ...
