Research paper

It's been a while since my last post, but that doesn't mean that nothing has happened. I defended my thesis in late April, and luckily the panel seemed veryv impressed with my work, and had only minor remarks and comments for corrections. I was, therefore, awarded a grade of 12 (highest possible grade in Denmark).
I am currently working with my supervisor, professor Zhan, on a possible release of the work as a research article in a scientific journal. With the both of us being busy with other work right now, it might be a while before this actually becomes a reality though. I will make sure to keep you posted on here.

Final Thesis Report

Here is the finished report. The thesis defense is taking place on the 29th of March at Navitas in Aarhus, Denmark. If you are interested in attending the defense or would like a copy of the appendix just send me an email (

First results from experimental setup

With all of my classes and finals being over I'm now able to focus my attention on the StackHR project and writing my thesis. I have been making a lot of progress on the project lately, so I think it's high time for a little update here on my blog!
For the thesis I'm focusing my attention on the heat recovery performance when operating at laminar and turbulent flow conditions. The setup basically consists of the coaxial heat exchanger "ventilating" a "room" that is represented by two plenum boxes. The two boxes are connected with a duct, through which I'm moving air with a couple of small PID controlled desktop computer fans. The fan speed is varied so that a pressure differential between the two boxes, equal to what would naturally occur due to stack effect in a full size setup is maintain at all times.
Below are a couple of pictures of the actual setup:

I have already gathered a bunch of data, and I have been really surprised by how reliably the …
