  1. CFD Lab Meeting 10/24/2005 Alan Lai

  2. Investigate Cp Anomaly • Checked Math, Checked Code • Unrealistic Cp due to unrealistic conditions • Validate Cp results • Generate Cl and Ct data and compare to result obtained by K.D.Jones and Platzer using Euler Code from AIAA 2002 Reno Conference

  3. Investigate Cp Anomaly • Checked Math, Checked Code • Unrealistic Cp due to unrealistic conditions • Validate Cp results • Generate Cl and Ct data and compare to result obtained by K.D.Jones and Platzer using Euler Code • Oscillatory Flow • Ran a preliminary case with fix alpha of 10 degrees at reduce frequency of 10 • Ran high res. Case with 500 step per period. • Results were unrealistic due to bug • Bug was fixed, will re-run case later today. • Weekend Project • Develop emblem for our lab • Begin work on updating website

  4. Investigate Cp Anomaly • Checked Math, Checked Code • Unrealistic Cp due to unrealistic conditions • Validate Cp results • Generate Cl and Ct data and compare to result obtained by K.D.Jones and Platzer using Euler Code • Oscillatory Flow • Ran a preliminary case with fix alpha of 10 degrees at reduce frequency of 10 • Ran high res. Case with 500 step per period. • Results were unrealistic due to bug • Bug was fixed and currently re running the case. • Weekend Project • Develop emblem for our lab • Begin work on updating website • Read Research Paper • “Unsteady Aerodynamic Model of Flapping Wing” Vest and Katz 1995 • “A Collaborative Numerical and Experimental investigation of Flapping Wing Propulsion” Jones, Castro, Mahmoud, Pollard and Platzer 2002 • Papers primarily studies low frequency flapping motion. • Viscous effect and aero-elasticity is very important to high frequency flapping flight
