Continuing Wind Tunnel Construction

Dear Fellow Basement Scientist,

We return to wind tunnel construction. Our extended absence in construction is unfortunate, but this is a lesson in many pursuits which are not our day job. These evening and weekend tasks often hit delays and sometimes we can’t return to them for a while. However, don’t give up. We may get discouraged and think our goals not worth attempting. Don’t believe this, have patience and return when the opportunity arises again. With diligence life often has enough little opportunities and breaks, so that after a few years of intermittent work, we can look back and be surprised at how much we’ve accomplished. So it is with basement science, and now we return to constructing the wind tunnel

Wind Tunnel Honeycomb

Dear Fellow Basement Scientists,

Here we are, placing the last finishing touches on the entrance to the wind tunnel. This is pretty exciting! We are discussing today what is known at the honeycomb. I very briefly mentioned this part of the project in Wind Tunnel Design Overview, but now we will discuss its purpose and construction.

So, if you remember, the purpose of the bell mouth entrance is to reduce all the whirly-twirly turbulence coming into the test section. Reducing this turbulence increases the accuracy and consistency of lift and drag measurements. Well, believe it or not, despite all our valiant efforts on the bell mouth, there is still turbulence in the flow. Bummer! Well, no worries because we can simply install a honeycomb to help us out (as a note, there is always some turbulence in this flow, we are just reducing it as much as possible). A honeycomb consists of lots of little tubes. These tubes kill turbulence because there can’t be big swirls in a little tube.  Here is a highly technical drawing laying out the details of this complicated phenomenon:

Surface of the Bell Mouth

Dear Fellow Basement Scientists,

I am sorry, but of late I have been absent. This is due to what is commonly known as moving. It was a lot of work, but now we are back.

For those concerned, I did move the wind tunnel! It required care and thought of how to pack it, but it is here and in its new location.  With honesty in mind, I must admit that it is no longer in a basement. Hmm, what to do? Should I relocate to a living quarters with a basement? Should I stop investigating because I no longer have a basement to conduct it? No! I shall make do with what I have and continue in the spirit of basement science! Our name shall remain because the spirit endures. Just because our laboratory is now above ground does not change our goals or opportunities. Thanks be to God. Let’s begin again.

Enter the Bell Mouth

Dear Fellows of the Basement Science Research Consortium,

For those new to the field, it is an important lesson to learn that the longer and more complicated the organization name, the more prestigious and talented the group. Therefore, we are part of a very important research group!

Our next task is to build the bell mouth. An overview of this was explained here a little earlier. I was trying to think of a good way to construct this as I was wandering though

Test Section Legs

Dear Fellow Basement Scientists,

Here we are, on to more construction. You may say, “What, I thought this was science not wood shop class!” Well, to conduct experimental science you have to build stuff. So, that is what we continue to do, building stuff to conduct our experimental science. Also remember, you have to build stuff right in order to get any good results.
