- This has *nothing* to do with my HP48 but as this is the only Bulletin
- Board that I know, I thought I'd post this here:
-
- Currently I'm studying Mechanical Engineering at the University of
- Strathclyde in Glasgow, Scotland and my fourth year project is to analyse
- the performance of shape memory alloys (SMA's) and to develop a small
- power generation unit utilising their characteristics.
-
- I would like as much information as possible on existing SMA heat engines
- from anybody who can supply it.
-
- I believe the Lawrence Berkeley Laboratory at the University of
- California demonstrated the first successful application of SMA's to a
- continually operating heat engine in August 1973. After that various SMA
- studies, including heat engines, were initialised at LBL principally
- under a grant from the National Science Foundation/RANN.
-
- Are these studies continuing today?
-
- What are the current maximum power outputs from these engines? My
- project has been "initiated" by the Ford Motor Company and they suggested
- a possible goal of 10 watts - rather optimistic in my opinion!
-
- The only books that I have access to are:
- Engineering Aspects of Shape Memory Alloys by T W Duerig et al 1990 and
- Shape Memory Effects in Alloys by J Perkins 1975 (source of the above
- information).
-
- Any information would be greatly appreciated.
-
- Thanks!
