A statistical design optimization study of a multi-chamber reactive type silencer using simplex centroid mixture design
(Sage Publications Ltd, 2021)
This study aims to optimize the acoustic performance of a silencer with baffles having extension tubes. It considers the position, the number and the extension geometry of the baffles as design variables and sound transmission ...
Effects of equivalence ratio and CNG addition on engine performance and emissions in a dual sequential ignition engine
(SAGE PUBLICATIONS LTD, 2020)
Compared to widening usage of CNG in commercial gasoline engines, insufficient but increasing number of studies have appeared in the open literature during last decades, while engine characteristics need to be quantified ...
A Study of Cloth Seal Leakage Performance Based on Geometry and Pressure Load
(MDPI, 2020)
Metal cloth seals have been used increasingly in gas turbines due to their flexibility and superior leakage performance. Leakage performance of a metal cloth seal depends on operating conditions, slot and geometric dimensions. ...
Experimental investigation of effects of single and mixed alternative fuels (gasoline, CNG, LPG, acetone, naphthalene, and boron derivatives) on a commercial i-DSI engine
(TAYLOR & FRANCIS INC, 2020)
A commercial i-DSI (Intelligent-Dual Sequential Ignition) engine is tested to investigate performance and emissions for single fuels and alternative fuels mixed into gasoline. The novelty of the study is the first time ...
Effects of alloy ratio and coating thickness on temperature distribution of thermal barrier coatings
(KOREAN ASSOC CRYSTAL GROWTH, INC, 2020)
Pistons on internal combustion engines that are constantly subjected to high pressure and temperature should be light, resistant to heat, resistant to corrosion and have adequate hardness to work more efficiently and to ...
Stress Analysis of an Arbitrarily-Shaped Structure with an Irregularly-Shaped Hole using Digital Image Correlation
(ELSEVIER, 2020)
Engineering structures commonly have arbitrarily-shaped geometry and contain irregularly-shaped cutouts. The integrity of these structures is significantly influenced by the boundary stresses associated with these cutouts. ...
The Effect of Solid Boriding Time on the Structure, Hardness and Corrosion Properties of AISI 5140 Steel
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2020)
In this study, AISI 5140 steel samples were borided in an electrical furnace at a temperature of 950 degrees C for 4, 6 and 8 h. Structural examinations, hardness measurement and corrosion tests were performed to determine ...
Effects Of The Boriding Process And Of Quenching And Tempering After Boriding On The Microstructure, Hardness And Wear Of AISI 5140 Steel
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2020)
An investigation was made on the effects of the boriding process and of quenching and tempering after boriding on the microstructure, hardness and wear of AISI 5140 steel. In this study, a new boriding agent (Baybora (R)-1) ...
Long-Term Stability of Ferroelectret Energy Harvesters
(MDPI, 2020)
Cellular polypropylene (PP) has been recently used in energy harvesting applications. In this work, we investigate its viability and long-term stability under various operating conditions. Specifically, the effect of ...
A Simulation Tool for Kinematics Analysis of a Serial Robot
(SPRINGER INTERNATIONAL PUBLISHING AG, 2020)
Robot programming is a very significant task in the field of robotics. Off-line programming (OLP) is a method performed before robot manipulation. It is the manual editing of the robot code using computer software to ...
