Intern - Direct Numerical Simulation of Combustion of Ammonia-Hydrogen Blends, R&D Grad Year Round
What Your Job Will Be Like
We are looking for an Intern - Direct Numerical Simulation of Combustion of Ammonia-Hydrogen Blends, R&D Grad Year Round
We are seeking a Intern to work on a priori analysis of ammonia/hydrogen blend and pure hydrogen turbulent combustion direct numerical simulation (DNS) data that has been produced over a range of pressures and equivalence ratios. The analysis will inform modifications to turbulent premixed flame wrinkling models, and in particular, augmentation that accounts for the contribution of thermo-diffusive instabilities.
On any given day, you may be called on to:
- collect flame-surface based statistics conditioned on progress variable, scalar dissipation rate and turbulent stretch
- develop plots that highlight trends in the statistical data
- write-up an analysis of the DNS results for inclusion in one or more journal publications
This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time.
NNSA Requirements for MedPEDs
If you have a Medical Portable Electronic Device (MedPED), such as a pacemaker, defibrillator, drug-releasing pump, hearing aids, or diagnostic equipment and other equipment for measuring, monitoring, and recording body functions such as heartbeat and brain waves, if employed by Sandia National Laboratories you may be required to comply with NNSA security requirements for MedPEDs.
If you have a MedPED and you are selected for an on-site interview at Sandia National Laboratories, there may be additional steps necessary to ensure compliance with NNSA security requirements prior to the interview date.
Qualifications We Require
You bring the confidence and skills to be eligible for the job by meeting these minimum requirements:
- Earned bachelor's degree
- Currently attending and enrolled full time in an accredited science, engineering, or math graduate program
- Minimum cumulative GPA of 3.0/4.0
- Ability to work up to 30 hours per week during the academic year, and up to 40 hours per week during the summer
- To be eligible for this position, applicants must be legally authorized to work in the United States of America, Sandia will not sponsor work authorization for this position
Qualifications We Desire
- Experience in direct numerical simulations of turbulent combustion
- Expertise in high-performance scientific computing
- Expertise in high-fidelity simulation of turbulent flows
- Strong communication skills
About Our Team
The Plasma & Reacting Flow Science department at Sandia primarily works on projects funded by the U.S. Department of Energy Office of Science to address needs surrounding both high temperature and low temperature plasma phenomena, combusting flows, reacting gas-solid interfaces, uncertainty quantification (UQ), and related topics such as scientific machine learning.
We operate state-of-the-art experimental laboratories, conduct work at the DIII-D tokamak reactor, and utilize both local computer clusters and the DOE Leadership Class supercomputers to conduct massively parallel simulations. We also perform numerical research to improve the understanding of advanced combustion engines, particularly when operating on low-C fuels.
This position does not currently require a Department of Energy (DOE) security clearance.
Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment.
If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.
Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals.
The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.
