PHASE 03 // DECOMPOSITION
The final structure takes the decomposition further by using only 120×120 cm, 1:50, surfaces. The aerodynamic strategy is, from direction 01: to capture the airflow and lead it through the structure, from direction 02: to capture the airflow and create turbulence.
An example of the decompostion of two surfaces. The goal was to capture the airflow and force it through the structure:
My first step in the decompostion phase was to simplify the model from phase 02, using only angles of 60 or 120 degrees to make construction easier:
The model with 12 elements, 10 connected. from phase 02 is decompositioned and optimized to fulfil the aerodynamic strategy:
3rd experiment with smoke. This time one compostion was made by a total of 12 elements, min. 10 of them connected. The composition for this model was inspired by the model 04 in the second experiment.
2nd smoke experiment. Two different compostions of own choice were made by 8 elements each, min. 6. of them connected. Each of the compositions had a ventialtion strategy: strategy 1 was to create turbulence from every direction, strategy 2 was to create turbulence from direction 1 and shelter from direction 2.
1st experiment in the new setup, based on compostions from earlier experiments to explore the aerodynamic effects in both plan and elevation. All were tested in two different directions.
We were introduced to a new 3-dimensional setup with an airtight box and smoke:
PHASE 01 // ELEMENTS AND DYNAMICS
In the fourth and final experiment of phase 01 four wall obstacles are used. The positions of the walls in the third and fourth part of the experiment were optional and thereby the first individual choice of experiment so far in this project.
Three wall obstacles are now used in the experimental setup.
In the four pictures below the position of one af the obstacles is varied to examine when the circular airflows occur and when the walls shield against the wind.
Another cardboard wall was added to the setup, now using a total of two walls. New results showing how the wind creates a kind of low pressure and circular or whirling airflows appeared and the space between the wall obstacles was varied to get a better understanding on what effect these airflows.
Below is an example of an experiment where the space between the two obstacles was varied in three different positions. The pictures show how salt in front of the second wall is removed, probably due to low pressures created by the wind passing on each side of the obstacles. As the second obstacle is moves further away, less salt is removed in front of it. This is probably due to less windforce.
The position of a single cardboard wall was varied to create different aerodynamic results in the experimental setup. All results were documented by camera and worked up into diagrams. Following are the results of the first four experiments.
On day 2 a setup for aerodynamic studies was made by a grid-box, some cardboard walls as obstacles, a blowdryer as the wind source, camera + holder to document to experiment, and lots of salt. This setup will be used for varied experiments throughout the project.
