Localised and bifurcating structures in planar shear flows
Published 2020“…The proposed model corresponds to the Z_2-symmetric pitchfork/Hopf problem, whose linear instability is the centrifugal instability. As long as the rotational symmetry is preserved, the system can have at most a pair of reflectional symmetric invariant two-tori, signifying the quasiperiodicity. …”

Simulation and study on cooling plant efficiency in green data centres
Published 2013“…By conducting background research on the leading standards in data centre design and benchmarking standards for energy efficiency, a model of a data centre and its cooling plant was designed and simulated using TRNSYS. The water cooled centrifugal chiller model used in TRNSYS was validated against the design of similar chillers used in other leading simulation software and data from the chiller manufacturer. …”

Quality assurance of vital® test meal in gastric emptying scintigraphy
Published 2024“…For the radiolabelling efficiency and stability experiment, 12 samples of Vital® were mixed with 99mTc-P, incubated with human saliva supernatant and gastric fluid for 4 hours, then centrifuged and filtered at hourly intervals. The radioactivity of the solid part and filtrate was assessed using 1-minute static imaging. …”

Numerical study of trapped vortex combustors characteristics in small ramjets
Published 2016“…Multiple secondary vortices and strong three-dimensional flows are observed in the cavity, so that the mixing is improved and a hotter cavity flame is generated. The centrifugal force effects, however, generate a short recirculation zone in the main combustor and concentrate the fuel stream on the combustor axis, which leads to deteriorate fuel-air mixing.…”

The road to federalism : finding the middle ground in Nepal, Myanmar and Sri Lanka
Published 2017“…Nepal, Myanmar and Sri Lanka are finding a middle ground whereby deliberative and moderating institutions are combined with accommodating ones to balance centrifugal and centripetal forces. Based on their experiences, I hypothesize that a federal system that encourages, if not requires, multiethnic political parties at the center, and ethnic parties in the units and sub-units provides a range of cross-ethnic, accountable, multilevel and semi-detached forums that incentivize moderation through deliberation, while accepting the validity and justice of ethnic autonomy and other accommodating institutions.…”

Experimental and numerical evaluation of aeroacoustic damping performance of in-duct double-layer orifice plates
Published 2017“…For this, a cold flow pipe system with double-layer perforated plates implemented is designed and tested in the Anechoic Chamber at Nanyang Technological University. A centrifugal pump is implemented to generate mean flow through the perforated plate. …”
