Acoustics analysis and test co-op
Cummins Emission Solutions-Applied Mechanics Team is looking for a student co-op/intern in the aeroacoustics field for Spring 2013.
Key Responsibilities:
➢ Identify governing flow induced noise mechanisms for typical aftertreatment system (muffler) designs
➢ Develop and document an analytical method for qualitative/quantitative prediction of tonal flow induced noise
➢ Assist in development and documentation of flow noise test method descriptions, definitions of design limits, and boundary condition/material property datasets
➢ Participate in Applied Mechanics team, define and help in identifying additional beneficial tools, equipment, software, and methods pertinent to flow induced noise prediction.
Most Critical Skill Dimensions:
➢ Familiarity with computational fluid dynamics / turbulent and laminar flow, internal flows, common dimensionless parameters
➢ Proficiency in linear analytical acoustics: duct acoustics, radiation from point and line sources into anechoic and semi anechoic spaces.
➢ Familiarity with aero-acoustics theory is a plus
➢ Ability to rapidly identify the aspects of component, system, or test design that most influence its acoustic characteristics.
➢ Familiarity with simple electronic circuit analysis, project management, and technical writing.
➢ Ability to learn and become proficient in the use of instrumentation, equipment, and software used in passive- and active-system acoustic characterization
➢ Ability to communicate test/analysis ideas, material needs, and project status clearly, concisely, and completely by telephone, in teleconferences, electronic mail messages, instant messages and reports.
Tools most commonly used:
➢ Pro/Engineer
➢ ANSYS/ Fluent
➢ Mathworks Matlab
➢ University of Kentucky VibroAcoustic Consortium – MAP (Muffler Analysis Program)
➢ LMS Test.Lab
➢ National Instruments LabVIEW & DIAdem, CompactDAQ
➢ Microsoft Office tool suite
