Computational Fluid Dynamics Air Flow Analysis Using Cosmos Floworks, we were able to simulate the air flow in real world conditions and analyze the effects at each targeted location. External flow parameters were used instead of internal flow. The locations modeled in Solid Works were: Babbio Center Howe Center Castle Point Apartments Each model included their respective rooftop structures to determine the effect they could be having on the directional component of air flow. Initial conditions and Boundary conditions were chosen to define the problem

CFD – Initial Conditions Our initial conditions were chosen to simplify the model and decrease solving time as well as give us a fairly accurate portrayal of what is occurring. Air was selected as the working fluid Initial Ambient Conditions Pressure at 101 kPA Temperature at K The velocity of the air in the X direction was set as 5m/s Through research, the average wind speed in the NYC area was 4-5 m/s Start up speed of the Whisper 200 is 3.1 m/s

CFD – Boundary Conditions Only one boundary condition was defined Walls of each structure The walls were defined as ideal walls which modeled them as adiabatic and frictionless. We chose not to model the walls as real because our analysis centered on the effect of each buildings geometry on the wind flow. Prove why Babbio is currently not sufficient Determine location where wind conditions are suitable Heat transfer coefficient, wall temperature and roughness factor were all negligible in our assumptions.

Anemometer Program Anemometer lacked a display device to show analytical data. DAQ from Design II Lab enabled the reading of voltage outputs from the sensors. LabView was utilized to create a user interface and log output feature. Anemometer was calibrated using Fluids Lab wind tunnel. See Appendix slides A&B for full program and interface.

Procedure Readings were taken with the Anemometer at 8 locations. Babbio, CPA, Howe, and River Lot All readings were taken within a two hour time period, as to reduce the effect of changing weather conditions. Experiment was repeated on multiple days. Results were analyzed to determine the best placement location for the Whisper 200.

Measurements and Results Sample was taken at Babbio Location A (original location) on Day 1 between 1:35pm and 1:45pm. Average Wind Velocity was measured to be m/s. Wind Direction was very sporadic. Each location was analyzed in this way on three separate days. (See Appendix slides for data)

Measurements and Results Sample was taken at CPA Location B (optimal location) on Day 1 between 3:00pm and 3:10pm. Average Wind Velocity was measured to be m/s. Wind Direction was conclusively consistent. After analysis, this location was chosen as the most optimal for the Whisper 200, due to its constant wind direction and reliable wind velocity.

Looking at the Future Phase IV Determine the power output of the wind turbine at new location Install data logger to see how much is being produced. How much money is saved? Monitor the wind turbine and see if any noise or vibration issues arise Use gathered data to tweak the design and improve energy production. Restrict the turning mechanism Develop channels to funnel the air
