Microchannel flow fields for polymer electrolyte fuel cells
… conditions, fuel cell component design and flow field design to name a few. The optimisation of the flow field design for water removal has primarily focused on the use of flow channels which are in the minichannel range. This study investigated the use of a microchannel flow field design …

Front Propagation and Feedback in Convective Flow Fields
… solutal and thermal feedback to the convective flow field is then studied by solving an exothermic autocatalytic reaction where the products and the reactants can vary in density. A single self-organized fluid roll propagating with the front is created by the solutal feedback while a pair of …

Intake flow fields for a zooplankton pump sampling system
The flow fields entering intake forms oriented into a steady flume flow has been observed and quantified. This data is applied to a model of zooplankton sampler performance, to predict the fraction of the sampled fluid from which no animals will escape under conditions similar to those of the …

Perturbed spherical objects in acoustic and fluid flow fields
In this study, the time averaged acoustic radiation force and drag on a small, nearly spherical object suspended freely in a stationary sound wave field in a compressible, low viscosity fluid is to be calculated. This problem has been solved for a spherical object, and it has many important …

Improved Gaussian process approximations for spatial and flow fields
… of interest is a function - such as a spatial or flow field - Gaussian processes (GPs) are suitable probabilistic models. These can incorporate expert knowledge (priors), and data can be used to learn the model parameters. The cost of learning is high, motivating approximations, most notably …

Fractionation & segregation of suspended particles using acoustic and flow fields
… The application of acoustic standing wave fields for the fractionation and segregation of suspended particles was studied. The above technology was implemented at the bench scale by building a Plexiglas chamber. Two ultrasound transducers were fixed to opposite sides of the chamber to …

Time-optimal multi-waypoint mission planning in dynamic flow fields
… the added complexity of a continuously changing flow field. The paths, or "legs," between all goal waypoints are generated by numerically solving exact time-optimal path planning level-set differential equations. The equations grow a reachability front from the starting location in all …

Flow fields created by impinging liquid jets and applications in cleaning
… sustainable cleaning systems, I have studied the flow field created by impinging liquid jets and their application in cleaning. On impingement of a liquid jet onto a surface, the liquid spreads radially outwards until it reaches a point where the liquid film changes its thickness abruptly. This …

Flow fields and heat transfer of liquid falling film on horizontal cylinders
A liquid film flowing over horizontal cylinders is of great importance as a high rate of heat transfer exists between the falling liquid film and the horizontal cylinders. The objective of this research is to use numerical predictions, following experimental verification, to study the flow field …

Some Features of Tip Gap Flow Fields of a Linear Compressor Cascade
… study of three-dimensional turbulent tip gap flows in the linear cascade wind tunnel, for two different tip gap clearances (t/c=1.65% and 3.3%). The experiments focus on near-wall flow field measurements for the stationary wall and moving wall, and static pressure measurement on the low …

Use of a Seven-Hole Pressure Probe in Highly Turbulent Flow-Fields
This work presents the experimental study of the flow generated in the wakes of three three-dimensional bumps in the Virginia Polytechnic Institute and State University Boundary Layer Wind Tunnel. The three bumps examined are named bump 1, small bump 3, and large bump 3, and are the same test cases …
