Its time to share another interesting photo. These interesting sights are often rare occurrences, because you must come across something interesting and have a camera with you. Also, you must be attentive enough of your surroundings to notice them. Well, I came across this sight, was very interested, and then returned with a camera. Walking around the downtown of my city, I stumbled on a cluster of trees who had learned the art of sharing, and shared their same space with a fence. What great models of friendliness and amazing display of biology:
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:
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.
