Transient method of characteristics via the Adiabatic, Theta, and Multigrid Amplitude Function methods
… Theta, and Multigrid Amplitude Function (MAF) methods for solving the Method of Characteristics (MOC) formulation of the time-dependent neutron transport equation. The transient transport versions of the 2D LRA and C5G7 benchmarks were used to assess the performance and accuracy of these …

Mass transfer in bubble column contractors
… for water and aqueous electrolyte solutions. Two methods were used to obtain experimental data on volumetric mass transfer coefficients: the steady state oxidation technique and a transient method. The former technique was found to be unsuitable for absorption measurements because chemical …

Fuel injection flow metering systems & test strategies for the characterisation of fuel injectors for future heavy duty commercial vehicles
… was designed to explore the effect of a transient method of characterisation of injector performance against expected performance with real world conditions. Finally the study has proposed an improved method for parameterising key features of injection rate signals during injection …

Analysis of embryonic development in Tribolium castaneum using a versatile live fluorescent labelling technique
… of live embryos. In my work, I have used a transient method for strong, homogeneous and persistent expression of fluorescent markers in Tribolium embryos, labelling the chromatin, membrane, cytoskeleton or combinations thereof. I have used several of these new live imaging tools to study the …

Numerical and Experimental Studies of Natural Convective Heat Transfer From Vertical and Inclined Narrow Flat Plates and Short Cylinders
… rates from cylinders were determined by the transient method, which involves heating the model and then measuring its temperature-time variation while it cools. The average heat transfer rates from the flat plates were determined using a steady state method, which basically involved …

Infrared Thermography Techniques for Flow Visualisation and Heat Transfer Coefficient Measurement
… Despite this importance, practical computational methods that predict boundary layer state remain unreliable thanks to the sparse, scattered data on which they are tuned. There is a need for experimental methods that can diagnose the boundary layer state on a component and measure the resulting …

Characterization of anisotropy in organic-rich shales: shear and tensile failure, wave velocity, matrix and fracture permeability
… an alternative to pulse decay and crushed sample method, we explain the measurement of permeability in nano-Darcy range by complex transient method. We determined that errors can be generated as a result of heterogeneity when three oriented samples are used to examine the effect of lamination on …
