Waste Heat Recovery System Research

[nickbike]

Hello RE.com!
I've been lurking around this forum for awhile reading and trying to learn from the immense depth of knowledge that exists here.
I’m a graduate student at the Colorado State University Engines and Energy Conversion Lab and we are working on installing a waste heat recovery system to do some research on.
The quick run down of the system is:
Working Fluid: R245fa
Hot Side: 90C Propylene Glycol/Water from internal combustion engine exchanged through a plate HEX
Cold Side: Forced Draft Dry Condenser
Expander: Tesla Turbine

I am starting this thread to keep you updated on the progress of installing and commissioning the system, and in return, I would like to pose some questions that are refrigeration specific.

Feel free to ask any questions about the project. I'll gladly answer.

I've attached some pictures of our major components (condenser, plate HEX, and turbine).
