They twisted tape (TT) is quite small and will be up to full
temperature quite quickly. After that, they to not remove any more
heat. But the added turbulence continues. And seems to have
substantial impact. <br>
<br>
The test of the TT could easily be done in the Rocket stoves that
have been tested so many times. Does 1 or more TT have impact
there? <br>
<br>
TT is one of several major designs for turbulence. Looks like an
important topic for more study (and does not require fancy expensive
equipment.<br>

lengthy version of an Indian doctoral thesis. It
concentrates on one village and one type of stove, providing
extensive testing and good reporting on especially the
amount of fuel consumed (mostly for water boiling) and the
time taken to acquire it. <o:p></o:p></p>

</div>
<div>
<p class="MsoNormal"> 3. The main new feature is on using
a simple low cost means of getting swirl and thereby better
gas mixing. The addition is called a TT - twisted tape.
Seems like it is adding 5% to stove efficiencies (which
started in the 20-25% range), otherwise no changes to these
tradition stoves. The paper provides a good review of
almost everything else about simple stoves, including
comments on WBTs. The TTs should be applicable to Rockets,
TLUDs, etc.<o:p></o:p></p>
