Innovative Fluid-Structure Interaction Solutions with Unstructured Meshes

DESCRIPTION

This project focuses on unified treatment methods for fluid-structure interaction, allowing seamless analysis of both solid and fluid regions. We developed robust schemes for computing flow on moving and deforming unstructured meshes and coupled structural computation codes, enhancing accuracy in fluid flow analysis. Our code has been integrated into a general-purpose Computational Fluid Dynamics (CFD) software called FIDAP, which caters to various industries like turbomachinery, automotive, biomedical, and more. Our work has applications in both commercial and governmental sectors, benefiting organizations like NASA.

  1. Fluid-Structure Interaction Using Unstructured Meshes Small Business Innovation Research Fluent, Inc. Lebanon, NH INNOVATION Unified treatment of fluid-structure interaction solving solid and fluid regions in one sweep • ACCOMPLISHMENTS • Developed and tested robust and accurate schemes for computing flow on moving and deforming unstructured meshes • Coupled a code for structural computation (both deform- able bodies and rigid bodies with spring-mass-damper) to the code for fluid flow analysis • COMMERCIALIZATION • Integrated the code developed under this SBIR as an important part of a general purpose CFD code • Marketing and selling this general purpose CFD code under the name FIDAP • Broad commercial application of FIDAP includes turbo- machinery, automotive, chemical processing, material processing, biomedical, and offshore industries Deflection of Flexible Structure Behind Rigid Bluff Body • GOVERNMENT/SCIENCE APPLICATIONS • Useful to both NASA and the military in fluid-structure interaction problems in turbomachinery and in flexible and rotary wings 1993 Phase II, NAS3-27637, 12/01 NASA Contact – Nan-Suey Liu Company Contact – Stefano S.
