Undergraduate Student Positions
Current Openings

The SPhERe Lab has several available research positions for the Spring of 2015. Please see project descriptions below.

Project Descriptions
1. High-speed imaging of an air-assisted water spray

A recently designed water spray system will be characterized via high-speed imaging. The student will be responsible for the setup up an illumination and imaging system for characterizing both near and far-field behavior of an air-assisted water spray, subject to a range of air and water supply pressures. The student will further generate image processing codes for quantifying features of the spray.

Desired skills for hire: troubleshooting, photography, MATLAB, knowledge of fluid mechanics.

Skills/Topics learned through completion of project: optics, high-speed imaging, image processing.

2. Data acquisition center for distributed experiments

A variety of experiments are performed within the SPhERe Lab and each has their own equipment requirements. But, a central component of each experiment is the data acquisition and electrical box. Our current data acquisition and electrical box is not suited for equipment additions or easy-access. Therefore, the student will design and construct a modular control center for the data acquisition and electrical box that enables each experiment access with ease.

Desired skills for hire: soldering, basic machining and fabrication.

Skills/Topics learned through completion of project: design, heat transfer, circuits.

3. Image processing for automated feature identification

The student will develop a tool for automated feature identification in image datasets featuring flows with complex structure. The image processing methodology will be based on an existing MATLAB code, but will be adapted for use with multiple types of imaging data.

Desired skills for hire: MATLAB, statistics.

Skills/Topics learned through completion of project: image processing, flow and combustion imaging diagnostics.

4. Computational fluid dynamics (CFD) spray simulations for Engine Combustion Network (ECN)

The Engine Combustion Network is a collaboration among industry, academia and national labs to study the fundamentals of spray combustion in internal combustion engines. Towards this effort, a joint modeling-experimental approach is used to investigate the physics governing spray atomization and breakup. The work from this project will aid in the submission of computational work for the ECN 4 Workshop. The student will learn how to set-up and analyze spray simulation cases in CONVERGE, a commercially-available CFD software, in order to investigate atomization of a fuel spray. Results from these simulations will be post-processed and analyzed using MATLAB scripts.

Desired skills for hire: MATLAB, fluid dynamics, CFD, C/C++

Skills/Topics learned through completion of project: computational fluid dynamics, analysis of simulation results, hydrodynamic stability.

5. Design of a mount for use of Engine Combustion Network (ECN) Spray C and Spray G injectors in the High Pressure and Temperature (HiPT) combustion chamber

The Engine Combustion Network is a collaboration among industry, academia and national labs to study the fundamentals of spray combustion in internal combustion engines. The ECN has a number of standard fuel injector nozzles that are used to generate experimental data at multiple participating institutions, including two recently adopted injectors known as Spray C and Spray G. The injector body designs for Spray C and Spray G are different than injectors currently in use in the SPhERe Lab, hence, new mounts are required to test these nozzles in the SPhERe Lab High Pressure and Temperature Combustion Vessel.  The students will design, fabricate and test the mount for these new fuel injectors.

Two students will work on this project together, each responsible for one injector mount design. This can include one 1st or 2nd year student paired with a more senior undergraduate student.

Desired skills for hire: 3-D CAD, Machining experience.

Skills/Topics learned through completion of project: designing for high pressure and temperature applications.

6. Design of a custom fuel-injection orifice block to study the atomization of fully developed turbulent liquid jets

The SPhERe lab is interested in conducting optical measurements of fuel sprays under well-controlled orifice conditions. Typical injector orifices have short lengths such that the flow is undeveloped, leading to uncertainty in the nozzle flow boundary conditions for spray simulations. This project will focus on the design and fabrication of a long orifice length block for the injection of high-pressure liquid fuels in order to to generate sprays with fully developed turbulent flow at the orifice exit. The student will design and fabricate a block that attaches to the tip of an injector nozzle in order to control the flow. The custom orifice will be approximately 100 μm in diameter, 10 mm in length, and be able to withstand pressures of 200 MPa.

Two students will work on this project together, each responsible for one injector mount design. This can include one 1st or 2nd year student paired with a more senior undergraduate student.

Desired skills for hire: 3-D CAD, Machining experience, fluid dynamics.

Skills/Topics learned through completion of project: designing for high pressure applications, high-speed imaging.
