Slide 1

Dr. Hell Consulting and Engineering Dr. Ulrich Heck: Structural Analysis and Fluid Structure Interactions (FSI) utilizing I-deas and ADINA Part II: Fluid Structure Interaction This presentation contains vivified gifs (PowerPoint 2000 or higher required, full screen presentation) Presented at 2002 PLM Europe Conference in Stuttgart, Oct, 2002 More data about our organization and our reproduction administrations: www.dhcae.de Dr. Ulrich Heck

Slide 2

Dr. Hell Consulting and Engineering FLUID-Structure Interactions: Fluid stream causes misshapening or development of structure Moveable or deformable structure impacts liquid stream Applications or procedures (cases): Biomedical: Artificial heart valves, move through veins or supply routes Automotive: Flow in Pumps, valves, stream around auto parts Aerospace Flow around rockets, stream around airfoil segments Production Injection forming Dr. Ulrich Heck

Slide 3

Dr. Hell Consulting and Engineering Example Modeling Fluid outlet Solid locale (Membrane) Fluid Region as a rule: Fluid model: tetrahedral components Solid Model: different component sorts conceivable (shell, different 2d or 3d-strong) Fluid gulf Dr. Ulrich Heck

Slide 4

Dr. Hell Consulting and Engineering Integration of ADINA in I-deas as of now exhibited by A. Hodgson Dr. Ulrich Heck

Slide 5

Dr. Hell Consulting and Engineering Some uncommon medicines in I-deas for FSI-demonstrating Two separate FE-models: strong model and liquid model Definition of components with exceptional properties (e.g. material names) or limit conditions at the FSI limits and dividers I-deas-ADINA interface deciphers and readies the models Post-handling is conceivable in I-deas for both models independently Investigation of strong and liquid model: ADINA post-preparing Dr. Ulrich Heck

Slide 6

Dr. Hell Consulting and Engineering E h 2 r C 0 = Validation of ADINA FSI:Tube with flexible divider tube/stream properties: thickness r , range R divider properties: thickness h, Young\'s Modulus E wave engendering speed: ADINA figured out how to decide the definite wave proliferation speed ! demonstrating: transient FSI Dr. Ulrich Heck

Slide 7

Dr. Hell Consulting and Engineering Example: Valve model Flow around body Membrane settled in valve near liquid outlet weight at liquid bay speed in tube dynamic weight misshapening of layer resistance of valve Dr. Ulrich Heck
