Work Hours 40 hpw
City Morgantown/Pittsburgh
State WV
Description Purpose
This position is housed in the NRCCE Energy Programs Division (EPD) and provides support for the programs of the Research and Innovation Center (RIC) of the US DOE, National Energy Technology Laboratory (NETL) at the Morgantown and Pittsburgh locations.

The incumbent in this position will design, conduct, and analyze gas turbine blade and vane cooling experiments at NETL to evaluate cooling geometries and develop correlations for enhanced heat transfer. The incumbent will support test design and data analysis with CFD analysis. The incumbent will work in a team of NETL researchers whose responsibilities include: identifying specific heat transfer features for testing; assessing test article type (flat plate versus air foil) to enable collection of accurate and reliable test data; and designing modifications to the test rig to support specific test objectives. The incumbent is expected to disseminate the research by preparing and presenting technical papers and reports. The incumbent will also lend support to the analysis of related NETL aero-thermal projects.

Duties & Responsibilities
Responsibilities are functional in nature, and performed under supervision. Specific tasks include, but are not limited to:
1) Responsible for meeting task requirements of NETL and AECOM research managers in attaining goals established for the NETL Turbine Thermal Management team and RIC programs as delineated in the statements of work pertaining to funding awards supporting this position.
2) Responsible for providing R&D technical support for the NETL Turbine Thermal Management team.
3) Responsible for assisting the Turbine Thermal Management team on
a. Designing and conducting film cooling experiments; analyzing experimental data and evaluating the performance of various film cooling geometries such as cylindrical, tripod and shaped holes
b. Presenting technical findings during regular team meetings as well as workshops
4) Responsible for simulating (CFD) the conditions of experimental test facility to predict the performance of the test articles
5) Responsible for designing a new high temperature flow channel test facility. Perform essential calculations required to scale performance at engine operating conditions and develop a test matrix to identify relevant parameters and operating ranges
6) Active participation in group meetings of the Turbines Thermal Management team, well as other task related meetings
7) Analyzing experimental data from laboratory tests and published data from other authors.
8) Assisting in the preparation of technical papers, reports, conference papers, and annual and quarterly reports. All presentation material(s) and journal papers shall be sent through AECOM/NETL for review and comment before submission to external units for technical review for publication or for presentation.
9) Presenting the results of the research at technical conferences and publishing in archival journals.

Supervisory/Lead Role
This position reports to the Principal Investigator. The position will also have technical reporting responsibilities to AECOM and NETL personnel overseeing the NETL Turbine Thermal Management program.

Physical Demands
Strong eye-hand coordination, as well as the ability to finger and feel; ordinary communication and hearing; as well as strong visual acuity, near and far, depth perception, color and field vision are required to successfully perform the responsibilities of this position. Activities are predominantly non-manual though some manual work may be included. Laboratory work will be required, and the incumbent is expected to adhere to safety and health protocols established by NETL and AECOM.

Work Environment
Work is performed in standard office and laboratory settings with shared equipment and light traffic. Moderate noise levels, exposure to electricity, fumes, and chemicals will occur. Use of protective clothing and/or equipment and compliance with safety precautions is required. The incumbent is responsible to know and comply with all safety procedures and to maintain all certifications required by NETL and/or AECOM as a condition of working on site at the NETL campuses.
