Overview

Overview

  • Refresh

  • Wind-Tunnel

  • Preliminary Model

  • CAD Models

  • Measurement Methods

  • CFD Progress

  • What’s Next


Refresh where were we

Refresh – Where were we?

  • Ideal angle of inclination is 51°

  • Too much weight for the roof?

  • Wind-Tunnel testing – Experimental

  • Computational Fluid Dynamics (CFD) - Computational


Wind tunnel spec set backs

Wind Tunnel – Spec. & Set-backs

  • Wind tunnel dimensions:

    Target area = 20% (total area)

  • Set-Backs:

    • Unsure about the state of the Wind Tunnel – Speculations say it is functional now!

    • Wind Speed – Hard to obtain (Repeatability Issue)

    • Availability of the Tunnel – Time conflict with other groups

20%

76.2 cm

137.2 cm


Preliminary model design

Preliminary Model – Design

  • 4-Leg Spider Model

  • Non-Repeatable & High errors

  • Complex MDoF Model

    Adapted for Final Concept


Preliminary model design1

Preliminary Model – Design

  • Screw-Bolt MDoF Model

  • Basic Hinge Model

    Simple/Cheap/ Repeatable | Poor


Cad models solidworks

CAD Models – SolidWorks

  • Screw-Bolt Multi-DoF Model created in SolidWorks


Measurement methods

Measurement Methods

  • Drag-Plate / Load Cells:

    • One directional force measurement

    • Only measures at a specific location

  • Pressure Taps:

    • Informed it is hard to set-up

    • Easy data acquisition / problematic analysis

    • Good Accuracy

  • ATI 6-Axis Force Transducer:

    • Budget Constrains: Delivery time / COST

    • Highly Accurate | Problematic Calibration


Cfd progress 2d modeling

CFD Progress – 2D Modeling

  • COMSOL Model:

    • Geometry – full size panel & 2D

    • Simple Physics – Laminar flow to begin

    • Complex system – Turbulent / Time-dependent

  • Boundary Layer Issues – Top/Bottom/Outlet

  • Convergence Issues


What s next where are we going

What’s Next – Where are we going?

  • Building the Experimental Model

  • Planning the Wind-Tunnel Schedule

  • Familiarizing with the Acquisition programs (Labview)

  • Proceeding with the CFD Models
