A new model for predicting the required pressure difference for pressure swirl atomizers
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2020)
Prior to this study an investigation is made to analyze the accuracies of the semi-empirical correlations of the previous studies by comparing them with a large number of experimental data which is extracted from the works ...
Fluid flow characteristics inside convergent, divergent and straight open-end pressure swirl atomizer
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2020)
Effects of geometrical parameters on the performance of small-scale open-end pressure swirl atomizers (PSA) have been studied using computational fluid dynamics. The shape of the swirl chamber is the main geometrical feature ...
Crucial topics in computer architecture education and a survey of textbooks and papers
(International Association of Engineers, 2020)
We have been teaching undergraduate computer architecture since 2012 in an unconventional way. Most undergraduate computer architecture courses are based on microprocessors, and they quickly move into advanced topics such ...
Micro-hydrodynamic interaction mechanisms in tio2 nano-colloidal suspensions with different particle size distributions: the effects of electrostatic and steric stabilization
(Bangladesh University of Engineering and Technology, 2020)
Micro-hydrodynamic interaction mechanisms of colloidal particles have important effects on the intrinsic properties and behavior of nano-colloidal suspensions, which in turn affect their different potential applications. ...
Design of energy-efficient white portland cement mortars for digital fabrication
(Springer, 2020)
Additive manufacturing, i.e. three-dimensional (3D) printing technology has many advantages over traditional processes and the related technology is continuously improving. This study aims to develop an energy- efficient ...
An experimental investigation into frost accumulation over vertical finned and unfinned surfaces during impinging air flow
(ASME, 2020)
Frost formation on evaporators negatively affects the cooling performance of refrigerators. It increases the thermal resistance between the refrigerant and air leading to a reduction in the system cooling capacity. In this ...
Taking inventory changes into account while negotiating in supply chain management
(SciTePress, 2020)
In a supply chain environment, supply chain entities need to make joint decisions on the transaction of goods under the issues quantity, delivery time and unit price in order to procure/sell goods at right quantities and ...
Preparation and characterization of freely-suspended graphene nanomechanical membrane devices with quantum dots for point-of-care applications
(MDPI, 2020-01-01)
We demonstrate freely suspended graphene-based nanomechanical membranes (NMMs) as acoustic sensors in the audible frequency range. Simple and low-cost procedures are used to fabricate NMMs with various thicknesses based ...
Effect of coating method on the surface characteristics of niti shape memory alloy
(Trans Tech Publications Ltd, 2020)
Metallic materials including stainless steel, cobalt-chromium alloys, titanium and its alloys, and nickel-titanium (NiTi) shape memory alloys have been used in biomedical applications since the 1940s due to their favorable ...
Evaluating the mechanical behavior of ARB processed aluminum composites using shear punch testing
(Trans Tech Publications Ltd, 2020)
Multi-layered metal composites have received considerable attention due to their improved mechanical and physical properties. In this study, Al6061/Al2024 composite was processed by accumulative roll bonding (ARB) as a ...
