Phase 2

Phase 2 was a continuation of phase 1. To investigate how the airflow in the models behaved in a wind tunnel. The fog could now reveal how the wind moved inside the struckture. Here we had the opportunity to work with spatial struktures, while still looking in the plane.

It was important to have a strategy for how the airflow should behave, to make the most out of the experiment. The orientation of the model was now important to think into the design, since this model should be places in the wind tunnel in two directions.

We should consider several assebbling possibilities for wood strucktures. They could either contribute to the design and be a part of the idiom, or hidden away. I have choosen to show two different ways to asseblme a 90-degree angle.

In this experiment i tried to make a symmetrical struckture to observe the small differences and what their effect on the airflow would be.

Here we can see how it creates turbulence inside the structure in one direction and turbulence behind the structure in the other direction.

Today we worked with 3D structures consisting of 8 elements, of which 6 should be connected. It was important that the structure was based on a strategy in regard to the wind. Afterwards they were tested in the wind tunnel, to see if our strategy worked out the way we thought it would.


The strategy for this setup was to   create some sort of funnel for the wind.
Turbulence behind the structure.


The strategy for this setup was to create a strong wind through the structure.
On the section image it showes how it creates turbulence behind struckture.

Pictures from yesterdays assignment with streamlines, that shows how the fog/airflow behaves in the structure.

#1

This setup is from phase 1. It was interesting to see if my theory about the airflow was as I expected. The fog showed how the air flow divides in two when it passes the surfaces.

#2

This one created turbulence in the middle in phase 1, but it didn’t look like it in the wind tunnel. But surprisingly it did create turbulence in the back of the side surfaces.

Phase 2 has begun. Today’s assignment consisting of a wind tunnel and a grid paper with an earlier arrangement from phase 1 I found interesting. The wind tunnel was used to visualize how the airflow moves in between the vertical surfaces with fog. The pictures from the experiment are to be drawn with streamlines.

The arrangement is placed in the wind tunnel in two directions, now we have to be aware of that the wind not only comes from one direction but two. Our final structure will also have more than one wind direction.

Phase 1

Phase 1 has been our initial work torch basic knowledge about aerodynamic. Through experiments with disconnected vertical surfaces, we have achieved an understanding about their influence on the airflow around them.
The setup which consisted of a box with a small layer of salt, vertical surfaces, placed differently at each experiment and a blow dryer to simulate airflow. . The orientation and arrangement of the blow dryer and surfaces has been in the main focus, through the experiments. Many parameters had influence on the resulting pattern in the salt, therefore it was important the keep all parameters consistent. The last two experiments had focus on creating a laminar or turbulent flow.

#16

Here the center of the box is sheltered.

#15

The slanted walls seems to create turbulens in the middle of the box.

#14

The airflow seems to create a laminar in the middle, between the surfaces.

#13

The three surfaces in the middle is simelar to experiment_09. The surface in outside the stairshaped structure in the middel stays unaffected.

#12

The salt along the slanted wall removes much faster than the salt along the straight wall.

#11

The salt along the slanted wall removes much faster than the salt along the straight wall.

#10

The surface in the center creates a pattern similar to Experiment_01 and could be the reason to the clear spots in the two frontal surfaces.

#09

The surface in the center of the grid seems to be more exposed to the airflow, which results in a minor amount of salt infront of it. However some sort ot turbulens might influence the salt disapering behind the surface in the front.

#08

The Airflow creates a tale of salt behind the surface, which is sheltered from the airflow. The same happens to the surface behind.

#07

The experiment i almost simular to experiment_03 except the Surface on the right stays almost unaffected.

#06

The overlap the two surfaces creates, seems to affect the amount of salt that disapears behind the frontal surface.

#05

The salt seems to stay unaffected when the surfaces are located too close or too far to each other.

Day 02
Wednesday, february 2nd, 2011

#04

The salt creates a asymmetrical pattern.

#03

The Airflow creates a tale of salt behind the surface, which is sheltered from the airflow.

#02

The hair dryer is placed in the middle of the grid and the surface is pushed to the right, which results in a asymmetrical pattern.

#01

The salt creates a symmetrical pattern. It looks like the airflow is  thrown back towards the hair dryer and then back and at the surface and along the sides.
