Representations of finite element tensors via automated code generation
(2009-02-26)
We examine aspects of the computation of finite element matrices and vectors which are made possible by automated code generation. Given a variational form in a syntax which resembles standard mathematical notation, the ...
HDPE (CM1) optical birefringence pattern in cross-slot flow, piston speed 2.64mm/s, 175C
(2008-09-05)
The optical birefringence pattern obtained from lightly branched high density polyethyene (HDPE - produced by metallocene catalysis polymerisation) flowing in a cross-slot multi-pass rheometer cell. Experiment carried out ...

Ignition of bluff-body methane flames
(2009-05-21)
The movies show the ignition process following a spark in a bluff-body stabilised methane non-premixed flame. The flow is described in: S.F. Ahmed, R. Balachandran, T. Marchione, E. Mastorakos, Spark ignition of turbulent ...
Ignition of spray flame with multiple spark
(2009-05-25)
The movies have been taken at 4000 fps. The spark is placed at a distance z from the nozzle and at 5mm from the enclosure. The ignition unit delivers at 100Hz a spark lasting 8ms, followed by 2ms of no activity. The front ...
Flame in methane jet after spark ignition
(2009-05-21)
The video shows the flame motion following spark ignition in a turbulent methane jet. The flow conditions were: 30% air, 70% CH4, jet velocity 12.5m/s & 25m/s, framing rate 4200 fps, spark at r=0, z=40d (40 jet diameters; ...
DOLFIN: Automated finite element computing
(ACM Transactions on Mathematical Software, 2010)
We describe here a library aimed at automating the solution of partial differential equations using the finite element method. By employing novel techniques for automated code generation, the library combines a high level ...
