WELLSTRESS V5 is NOW FREEWARE!!
USA — June 18, 2006 — Dr. David S. Bartran’s free and popular engineering program for calculating flow-induced vibrations and resonances in thermowells, WellStress, has been upgraded to version 5.
It is freely available as a download on this website to any and all registered users (registration is free), as are the earlier versions.
To those seeking V4, do not waste your time, it was modified before it went to distribution.
To those who have had problems downloading V3, the first zipped version; we apologise, the problem is fixed and you may now compare results between versions, if you wish.
NOTE WELL: This software is NOT FOR NEWBIES!
USERS AGREE TO ASSUME ALL RESONSIBILITIES FOR ANY UNINTENDED CONSEQUENCES WHEN THEY DOWNLOAD.
(NOTE: THIS VERSION IS IN COMPRESSED, ZIP FORMAT. That helps keep the download reasonable. The unzipped version is over 270 Kb, while the zipped one is about 85 Kb. That can mean a lot to someone with a 12 kb modem; they still exist! There are several free and low cost programs with free demos on the Web that can extract the .exe file from the compressed form such as those found on www.winzip.com and www.pkware.com ).
If you are unable to access the files for download or extraction of the the executable program from the compressed format, drop me an email at grpeacock@tempsensor.net, and I will do my best to help you get what you seek.

Thermowells are subject to more than just the static forces from the fluids going past. They also can have vibrations induced from the fluid vortices in the wakes (the von Karman wakes) created by the interaction between them and the fluids. This has been known for a very long time and it is most significant in the realm of highly energetic flows.
The induced vibrations are very critical when their frequency corresponds to the resonance frequency of a thermowell . Under such conditions, the temperature sensors can literally be pounded to pieces. The thermowells themselves can rupture in extreme cases.
