Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

Creator:: Mohammadi, Mahshid
Abstract:: A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

A Computational Fluid Dynamics Investigation of Hemolysis Potential in a Microfluidic Hemoperfusion Device Designed for Use in Sepsis Treatment

Creator:: Myers, Karl N.
Abstract:: The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...

Water treatment technologies for the developing world

Creator:: Burleson, Grace Ellen
Abstract:: The intent of this report is to provide a brief description of water quality issues in Nicaragua, Uganda and Bangladesh, and the technologies available to address these issues. The water quality parameters considered include: bacterial contamination, heavy metals and arsenic, pesticides and industrious chemicals, turbidity, radiological characteristics, and taste and...

Analysis of spillway hydrodynamics for total dissolved gas prediction downstream of hydropower projects with free, plunging spillway jets

Creator:: Germann, Nathan A.
Abstract:: During spring and early summer hydropower projects are often forced to spill water through their spillways due to increased river flows of the runoff season. Flows which are directed through spillways--instead of through turbines--contain a substantial amount of energy. Stemming from the high energy content, spillway flows entrain air at...

Improving Water, Sanitation and Biogas Access in Resource-Stressed Environments : Methodologies and Case Study Analyses of the Primary Resources at Matema Beach High School

Creator:: Richardson, Megan M.
Abstract:: Education as a right has taken off internationally with expanded national policies in recent years. Across Africa over 80% of countries have abolished tuition fees for primary education and several have made the leap to free secondary education as well. With decreased financial barriers keeping kids out of the classroom,...

Experimental study of impulse turbines and permanent magnet alternators for pico-hydropower generation

Creator:: Cobb, Bryan R.
Abstract:: Increasing access to modern forms of energy in developing countries is a crucial component to eliminating extreme poverty around the world. Pico-hydro schemes (less than 5-kW range) can provide environmentally sustainable electricity and mechanical power to rural communities, generally more cost-effectively than diesel/gasoline generators, wind turbines, or solar photovoltaic systems....

Characterizing Linkages Between the Climate, Cryosphere, and Impacts on Run-of-River Hydropower in Data-Sparse Mountain Environments

Creator:: Mosier, Thomas M.
Abstract:: In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...

The Role of Contact Line (Pinning) Forces on Bubble Blockage in Microchannels

Creator:: Mohammadi, Mahshid and Sharp, Kendra V.
Abstract:: This paper highlights the influence of contact line (pinning) forces on the mobility of dry bubbles in microchannels. Bubbles moving at velocities less than the dewetting velocity of liquid on the surface are essentially dry, meaning that there is no thin liquid film around the bubbles. For these “dry” bubbles,...

Integrated Evaluation of Drinking Water Purification: A Mixed-Method Laboratory and Field Assessment of a Biomass-Powered Water Treatment Technology

Creator:: Burleson, Grace Ellen
Abstract:: The global water crisis is defined as one of the major threats facing humankind over the next decade with over 1 in 10 people lacking access to clean drinking water worldwide. An estimated 1.2 million people pasteurize their drinking water by using boiling as an indicator. Pasteurization is the process...

Little green baby steps : transforming modern power production through microscale hydropower

Creator:: Holderman, Jennifer A.
Abstract:: Microscale hydropower, facilities that produce between 1 kW and 1 MW of power, has the potential to revolutionize modern power production. Unlike conventional large scale operations, these water supplies can be utilized with little impact on the environment. Hydropower per unit production can be very affordable compared to other renewable...
