An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...
A unique mass-flow control system for the carrier gas
in gas chromatography is described and evaluated. Carrier
gas flow is controlled by a flow sensor, feedback electronics,
a flow-control valve and a microcomputer. The
flow-rate is monitored by a mass-flow meter by this system
and the flow is adjusted in...
Mixing of ferrite tracer with silica sand was studied in a 0.91 m
x 0.91 m cold fluidized bed. Inductance probes located Inside dummy
heat transfer tubes [in a 4 x 4 x 4 array] were used to monitor a
ferrite tracer with physical properties similar to coal as it...
Large Eddy Simulations (LESs) for a lean-direct injection (LDI) combustor are performed and compared
with experimental data. The LDI emissions characteristics, and radiation-spray coupling effect on the predictions
are analyzed. The flamelet progress variable approach is employed for chemistry tabulation coupled
with a stochastic secondary breakup model. Good comparisons are...

The purpose of this study is to determine whether a 12-week nutrition and physical activity (PA) intervention program for middle-aged, pre-menopausal women at risk for Metabolic Syndrome (MetS) would reduce their risk factors. Ten overweight women (mean ± SD: age = 47 ± 3y; Body Mass Index = 31.0 ±...
Winegrapes are an important crop for Oregon agriculture, ranking amongst the top ten agricultural commodities based on farmgate value. The most widely planted winegrape cultivar in the state is ‘Pinot noir’ (Vitis vinifera L.), and the majority of acreage is produced in the Willamette Valley. Production of quality ‘Pinot noir’...
