Wind tunnel, day 1

Model 1

In this picture you can see how the airflow hits the walls and is spread to both sides. In the middle of the two walls winds traveling in each direction meet and hit yet another wall. The airflow going under the middle wall seems to be more interrupted than the one on top. This might be because of a third wall that seems to break down the upper wind, now coming from only one direction.

Model 1 turned 180°

When the composition is turned 180° the diagonally placed walls create meeting winds and turbulence can be seen behind the two first diagonal walls.


Model 2

The diagonally placed walls lead the airflow in but it’s like there’s not enough space in the corner for it to pass through. Some turbulence occur. But also the wind that passes through hit a meeting wind and make a greater turbulent system.

Model 2 turned 180°

Turning the model 180° makes less wind go through the walls. In the upper corner some wind is lead in, but it looks like it bounces between the two walls. The second wind comes through beneath the vertical wall and meet the bouncing wind, but it seems as it has enough space to calm down and don’t effect any other airflows. When the passing wind through, and the wind going outside, the diagonal walls meet, turbulence occur.


PHASE 1

Observations, day 4

Even if the airflow’s natural path would be between the two diagonal walls, some of it actually passes on the outside of the upper wall and hits the horizontally placed wall. I found it interesting that the airflow even hit the wall placed on top.



Here I wanted to observe how horizontal and diagonal walls interfere with the airflow. One wall was placed facing the hair dryer to spread the wind. The wall placed in an angle took up most of the airflow. The diagonally placed walls lead less of the airflow, but this also due to the arrangement of the walls and the natural orientation of the airflow.
