Novel mechanism of instability control using tapered spike in hypersonic flow
(American Institute of Aeronautics and Astronautics, 2021-08-02)
A forward facing spiked blunt nose in high-speed flows is associated with pulsating flow behavior of varying amplitudes depending on spike-nose and length, the forebody geometry and flow conditions. A tapered spike has ...
Fundamental limits of measurement in telecommunications: Experimental and modeling studies in a test optical network on proposal for the reform of telecommunication quantitations
(IOP Publishing, 2011)
Proposals for a review of the limits of measurement for telecommunications are made. The measures are based on adapting work from the area of chemical metrology for the field of telecommunications. Currie has introduced ...
Microfluidics in haemostasis: A review
(MDPI, 2020)
Haemostatic disorders are both complex and costly in relation to both their treatment and subsequent management. As leading causes of mortality worldwide, there is an ever-increasing drive to improve the diagnosis and ...
On unsteady flow analysis of a round spike blunt nose afterbody in mach 6 flow
(IOP Publishing Ltd, 2021)
An aerospike, in front of a blunt body, has largely been deemed as a key passive control device for effectively reducing the wave drag and aerodynamic heating associated with high-speed flows. In addition, it has been ...
Pulsating flow investigation for spiked blunt-nose body in hypersonic flow and its control
(American Institute of Aeronautics and Astronautics, 2021-01)
An aerospike, as a technique for drag reduction and heat transfer in high-speed flows, is
associated with instabilities. To understand the pulsating flow behavior in front of forward
facing spiked blunt nose, numerical ...
CFD-CRN Study of NOx formation in a high-pressure combustor fired with lean premixed CH4 / H2 - air mixtures
(The American Society of Mechanical Engineers, 2021-01)
The main motivation of this study is to investigate detailed NOx and CO formation in high-pressure dump combustor fired with lean premixed methane-air mixture using CFD-CRN hybrid approach. Further, this study is extended ...
The impact of thermal degradation on properties of electrical machine winding insulation material
(IEEE, 2016)
Interturn stator short circuits can develop quickly leading to serious damage of an electric machine. However, degradation mechanisms of winding insulation material are not yet fully understood. Therefore, the main ...
Study of direct gas injection into stagnation zone of blunt nose at hypersonic flow
(American Institute of Aeronautics and Astronautics, 2021-07-28)
Direct gas injection in the shocked or compressed region has importance in many applications from drag control to ignition and pressure gain combustion. This numerical study is focused on direct light gas injection into ...
A new optical method of continuously analysing the surface properties of a single pendant drop while obtaining quality bulk spectral and refractive index measurements of the liquid-under-test
(IOP Publishing, 2009)
The classical stalagmometer has been replaced by the tensiometer to measure surface properties from drop volume. From the drop period T1, converted into volume, the surface properties of the liquid can be obtained. In the ...
An Open-Source Testbed to Visualise ICS Cybersecurity Weaknesses and Remediation Strategies – A Research Agenda Proposal
(IEEE, 2021-07)
Industrial Control Systems (ICS) are responsible for the control of several processes in various critical infrastructure deployments ranging from energy, power and water utilities, to manufacturing sectors such as ...
