AHPCRC Bulletin: Fall 1996 - Volume 6 Number 41996 Summer Undergraduate Internship Program in HPC in Fluid DynamicsAnita Anderson (AHPCRC-UM)For the past several years the AHPCRC has co-sponsored a Summer Undergraduate Internship in High Performance Computing (HPC) in Fluid Dynamics. The funding for this program is provided mainly by a National Science Foundation grant to the University of Minnesota (UM) Department of Aerospace Engineering and Mechanics (AEM). In addition to promoting undergraduate involvement in HPC in fluid dynamics, this program also exposes undergraduate students to HPC and its applications in the science and engineering fields, and encourages students to pursue graduate studies in related areas.The 1996 projects, which are described below, were supervised by AHPCRC faculty from the UM departments of AEM and Computer Science (CS).
Kevin Chou is pursuing a degree from Cooper Union for the Advancement of Science and Art, New York, New York in electrical engineering with a minor in mathematics. His faculty supervisor for the internship program was Ahmed Sameh (CS), an AHPCRC-UM co-PI and coordinator of the AHPCRC Enabling Technologies Research Team. Chou and Sameh's project, "Parallel Algorithms for the Generalized Stokes Problem," used massively parallel distributed-memory machines such as the CRAY T3D and MIMD shared-memory multiprocessors such as an 8-processor CRAY C90. Larye Pohlman is pursuing a degree from Augsburg College, Minneapolis, Minnesota, in physics with minors in mathematics and computer science. His supervisor for the internship program was Graham Candler (AEM). Candler is an AHPCRC-UM co-PI and member of the AHPCRC Simulation and Modeling Research Team. The objective of the project, "Simulation of Chemically Reacting Flows," was to use a finite-volume method to solve the Navier-Stokes equations to simulate the flow within a new natural gas burner.
Figure 1 shows the Mach contours for a compression corner flow. The boundary layer at the leading edge of the plate causes a weak shock wave to form. The boundary layer and recirculation zone at the corner of the plate and wedge can also be seen in the Figure. Finally, the shock wave formed at the corner is also visible.
Natasha Shekdar is pursuing a degree from Brown University, Providence, Rhode Island, in civil engineering with emphasis in structures and environmental problems and planning. Her supervisors for the internship program were Vinay Kalro (AEM), member of the AHPCRC Simulation and Modeling Research Team, and Tayfun Tezduyar (AEM), PI and Director of the AHPCRC, and the coordinator of the AHPCRC Simulation and Modeling Research Team. The objective of the project "Parallel Finite Element Simulation of Fluid Flow Applications: From Mesh Generation to Flow Visualization" was to involve undergraduate students in the process of numerical simulation of real-world flow problems. Figures 2 and 3 show results from 3D simulation of flow through a flexible pipe, with the structural response of the pipe determined as part of the overall solution.
A national competition for candidates for the 1997 Summer Undergraduate Internship Program in HPC in Fluid Dynamics was concluded in February 1997. Six to eight interns are expected to participate in the Program, during the period June 16 through August 22. The 1997 summer projects are listed in Table 1.
