Enabling Ultra-High Diesel Engine Efficiencies Through Flexible Valve Actuation
|Research categories:||Mechanical Systems|
|Preferred major(s):||Mechanical Engineering|
|Desired experience:||Thermodynamics, measurement systems; if possible: IC engines, control systems|
|Number of positions:||1|
The Purdue team is focused on improving the efficiency of diesel engines through flexibility in the valvetrain. As one example, cylinder deactivation allows increases in efficiency, and exhaust gas after treatment effectiveness, via reduction in airflow and pumping penalty when 2, 3, or 4 of 6 cylinder are deactivated (both fueling and cylinder valve motions are deactivated). The Purdue team utilizes both simulations and a unique multi-cylinder engine system to study this and other strategies. The project includes funding from, and interaction with, both Cummins and Eaton.
In Situ Strain Mapping Experiments
|Research categories:||Aerospace Engineering, Civil and Construction, Computational/Mathematical, Computer Engineering and Computer Science, Industrial Engineering, Material Science and Engineering, Mechanical Systems|
|School/Dept.:||School of Aeronautics and Astronautics|
|Preferred major(s):||AAE, MSE, or ME|
|Number of positions:||2|
The research we do is building relationships between the material's microstructure and the subsequent performance of the material, in terms of fatigue, fracture, creep, delamination, corrosion, plasticity, etc. The majority of our group’s work has been on advanced alloys and composites. Both material systems have direct applications in Aerospace Engineering, as we work closely with these industries. We are looking for a motivated, hard-working student interested in research within the field of experimental mechanics of materials.
The in situ experiments include advanced materials testing, using state-of-the-art 3d strain mapping. We deposit self-assembled sub-micron particles on the material’s surface and track their displacement as we deform the specimen. Coupled with characterization of the materials microstructure, we can obtain strain localization as a precursor to failure. Specific projects look at increasing the structural integrity of additive manufactured materials and increasing fidelity of lifing analysis to introduce new light weight materials into applications.
