Steam distillation has been the common method of extraction of essential oils from plants for more than a century. The use of microwave energy has been suggested as an alternative distillation method that would: reduce water usage, dependence on non-renewable energy sources, and the carbon footprint. A byproduct of this...
An in-field test of the solvent free microwave extraction of peppermint oil was held in mid-August 2009 at Butler Valley Farms in Stayton, Oregon. Results of the trial were limited due to rapid coalescence of the mint oil prior to entry into the separator. This resulted in no mint oil...
Computational fluid dynamics conjugate heat transfer simulations were performed on a packed bed test facility using Dowtherm-A as the working fluid. Multiple test cases were simulated for a Reynolds number range of 188 – 1524 and a set heater power of 60 kW. Temperature profiles were extracted, and the near-wall...
This work develops the Global Formula Racing computational fluid dynamics (CFD) model in StarCCM+ to allow for vehicle attitude studies to be ran to evaluate Formula Student (FS) vehicle aerodynamic loads. Attitudes that this model allows to be studied include roll, pitch, yaw, heave, tire angle, and vehicle speed. The...
Current AASHTO-LRFD specifications use many disparate design provisions to establish live load demands in bridge decks. As an example, approximately 17% of Chapter 4 addresses the analysis of decks. One of the AASHTO-LRFD analysis methods for decks uses an orthotropic plate model. The present AASHTO-LRFD orthotropic plate model has a...
Can a wellness movement and business be an American religion? By tracing three threads of historic American religions - New Thought, Christian Science, and Scientology - we can see how we've arrived at the place of even entertaining the question of GOOP as an American religion.
