Grundfos Pumps is seeking two (2) Mechanical Engineering Interns from Texas A&M University to join our team. These Engineering Interns will work daily to assist in various projects that supports increasing the reliability of parts and motors used to support the overall quality of pumps products we produce. This full-time internship opportunity will work out of our Brookshire,Texas facility as a member of the US Tech Center team. The hours for this position are 8:00 am-5:00 pm, Monday-Friday. Note: We cannot offer work sponsorship support for this internship.

Project Opportunities:

Project 1: Fatigue Simulation of Composite Impellers
Project Description:
Composite parts offer cheap and flexible manufacturing. Composite impellers (plastic with glass filling) are currently only used in small centrifugal pumps (up to 2 kW), largely limited by fatigue concerns of the blades of the composite impeller. Investigate potential methods (both analytical and testing) which can be used to better understand and predict fatigue failure of composite impellers.
Project context to Grundfos product development and engineering:
  • Accurate simulation and modelling is crucial to agile product development and Grundfos has ventured this for more than a decade.
  • Creation of numerical models and/or test methods is supporting this venture and improved understanding will be crucial in extending the current application limit for composite impellers.
  • The student will specifically be working with investigating potential methods (both analytical and testing) which can be used to better understand and predict fatigue failure of composite impellers.

As part of this, the student will specify and conduct a series of specific tests. The result is expected to be a report presenting and substantiating the findings as well as a verbal presentation of the conclusions to an internal specialist audience.
Project 2: Experimental and Numerical Correlation of Fire Pump Cavitation Data
Project Description:
The focus of this study is to correlate test data with CFD results for a split-case double-suction fire pump, with the aim of gaining insights into cavitation phenomena under different testing conditions. Experimental data was produced for a series of NPSH and suction lift test conditions, along with multiphase CFD simulations. The objective of this project is to collect and correlate data from NPSH tests and NPSH CFD simulations, to gain insight into the suction lift performance of centrifugal pumps.
Project context to Grundfos product development and engineering:
  • This project will help define a robust design criterion based on CFD simulations, which can be used in the hydraulic design process to better predict if new pump designs will pass the suction lift test requirements according to fire pump standard specifications.
  • The student will specifically be working with correlation of NPSH test and simulation to create a robust design criterion.

The result is expected to be a report presenting and substantiating the findings as well as a verbal presentation of the conclusions to an internal specialist audience.
Project 3: Test Stand Design for Journal Bearing Design Verification
Project Description:
Journal bearings can be used in centrifugal pumps to support the radial loads created by the impeller. Lifetime performance of the journal bearing is influenced by several factors, including bearing pressure, surface velocity, media temperature, and media viscosity. The objective of this project is to design a test stand which can be used to apply load to journal bearings and determine the relationship between applied load and bearing lifetime.
Project context to Grundfos product development and engineering:
  • A better understanding of the critical parameters for journal bearing design will improve the reliability of pumps and motors which use journal bearings to support radial loads.
  • The student will specifically be working with designing a test stand which can be used to apply load to journal bearings and determine the relationship between applied load and bearing lifetime.

The result is expected to be CAD models and drawings for the design and a report presenting and substantiating the findings as well as a verbal presentation of the conclusions to an internal specialist audience.
Project 4: Failure Characterization of Gray Cast Iron
Project Description:
Gray cast iron is a non-linear, brittle material which is used in several components of a centrifugal pump. The non-linear behavior of the stress-strain curve needs to be considered to accurately determine the failure load (e.g., burst pressure) of a gray cast iron component. The Modified Mohr failure theory is typically used to estimate the stress states which result in fracture of gray cast iron. Multi-axial material testing of gray cast iron can be used to compare the actual failure envelope with the theoretical failure envelope (i.e., Modified Mohr).
Project context to Grundfos Product Development and Engineering:
  • This test data can then be utilized in the new product development process, reducing uncertainty in the safety margin between working pressure and burst pressure.
  • The student will specifically be working with determining non-linear cast iron material models, both testing and analytical. Determining the failure criteria for the non-linear material model.

The result is expected to be a report presenting and substantiating the findings as well as a verbal presentation of the conclusions to an internal specialist audience.
Project 5: Production Checker for Cast Impellers
Project Description:
The casting process has several production constraints (draft angles, minimum castable thickness, pull-able cores etc.). A tool for evaluating the cast-ability of designs in the early development phase would be very beneficial. The objective of the assignment is to create an evaluation tool that quickly evaluates the cast-ability of a casted impeller.
Project context to Grundfos Product Development and Engineering:
  • Find good evaluation method of casted impellers, enabling a fast cast-ability check in the development phase.
  • The student will specifically be working with developing a casting evaluation tool for casted impellers.

The result is expected to be a report presenting and substantiating the findings as well as a verbal presentation of the conclusions to an internal specialist audience.

Qualifications:

Seeking Junior, Senior (preferred) and Graduate (preferred) students, or recent graduate, focused on mechanical engineering and have some experience and knowledge of CAD, Drafting, Mechanical Design, Tribology, Physical experimentation, FEA, Mechanical Measurements CFD, Pump Design, Fluid Mechanics Physical prototype testing is preferred.
Individuals must be good communicators, detail oriented and ability to partner with various departments on projects where applicable. Self-Starter who can take the initiative to drive results. This Intern should be comfortable engaging with other individuals, asking questions and sharing ideas. Interested students should submit their resume and a cover letter explaining their interest in this internship.
