UW ChE Student Presentations
Date
Tuesday, May 10, 2005
Speakers
and Topics
The following students will give presentations at the May 10,
2005
meeting of PSAIChE:
Speaker: Adam Oliver
Title: "The Effect of Temperature on
the Rheology of a New Liquid Toner"
Abstract: A new liquid toner is being
developed for operation in a printing process in which ranges between room
temperature and 70˚C. Poor
print quality and equipment jamming appear to result from unwanted viscosity
changes in the ink over this temperature range.
This behavior is quantified, and an explanation for it is determined.
Speaker: Yo Yamazaki
Title: "The Effect of Cationic Solutes
on the Wettability of Cellulose and the Strength Properties of Paper"
Abstract: Excessive cationic surfactant
material in the wet end of the papermaking process appear to have deleterious
effects on paper quality. This is
explained in terms of changes caused in cellulose fiber wettability, which is
measured and correlated with measured strength properties of hand sheet
specimens.
Speakers: Albert
Chang and Nicholas Tapias
Title: "Polymer
Mixing in Water Treatment"
Abstract:
A
group of chemical engineering juniors are working with Steve Drury, of Sharpe
Mixers, and Jim Pitts, of the Renton Wastewater Treatment Plant, to see if we
can suggest ways to reduce the amount of polymer used in one part of the process
(to cause coagulation). While
the entire physics can’t be simulated, critical parts can be, and the group is
working to do that. Some of the
group is measuring the non-Newtonian viscosity as a function of shear rate and
concentration, some are doing simulations of non-Newtonian flow and dispersion
in laminar flow in mixers using FEMLAB, and some are looking at the mass
transfer of chlorine from sodium hypochlorite that is put into the waste stream
before it is sent to Puget Sound (before it enters the long tunnel).
One junior is experimenting with viscoelastic flow in FEMLAB (which
hasn’t been done before), since the real situation involves viscoelastic flow.
The members of the group are Angelo Ambion, Albert Chang, Diana Chung,
Joanne Crompton, Dan Ho, Tian Huang, Toai Nguyen, Thin Thin Swe,
Nick Tapias, Sheena Vince Cruz, and Daniel Walker.
