Streams transport the products of erosion and weathering, as well as anthropogenic materials collected from industrial, agricultural and urban environments. While waterways are efficient transport networks, they are also important biogeochemical filters . Streams are known to efficiently retain and transform organic and inorganic nutrients. Microbial biofilms at the sediment-water interface purify the flowing freshwater. Streams are complex heterogeneous systems characterized by a tight coupling between the physical and biological template they inundate. This project will shed light on how dissolved chemical species move through riverbed sediments and their associated biofilms, with a focus on the nitrogen cycle and nitrate pollutions. Eutrophication of freshwater caused by fertilizers is a major societal issue. High loads of plant food lead to periodic oxygen depletion in receiving water bodies, causing major ecological and economical disasters. This project will inform sustainable management of water resources by providing a physically based explanation for the transport of solutes. The SURF students will work in the laboratory and/or in the field and they will acquire the hands on skills needed to complete a research project.
Design and Testing of a Novel Concept for Variable Flow Pumps
|Research categories:||Agricultural, Aerospace Engineering, Material Science and Engineering, Mechanical Systems|
|School/Dept.:||Ag & Bio Eng. / Mech. Eng.|
|Preferred major(s):||Mechanical, Ag and Bio, Aerospace, Material Engineering|
|Desired experience:||CAD modeling / fluid mechanics / fluid power / labview|
|Number of positions:||1|
The present project is aimed at realizing a prototype of a novel concept of pumps. The novel concept consists in realizing a variable flow regulation using the principle of external gear machines. The novel concept guarantees higher energy efficiency of the overall hydraulic system.
The student's contribution within this project will be the design of an actual prototype of the new concept, suitable to operate at a level of delivery pressure up to 10 bar. On the basis of fluid-dynamic simulation results, the student will design all internal parts and follow the manufacturing process. In the final period of the project, it is expected an experimental activity aimed at verifying the expected pump performance on a research test rig utilizing existing facilities at the Maha Fluid Power Research Center of Purdue.
