Talk:Uniflow steam engine

Advantages
Second paragraph of this section contains a very long sentence... EdJogg 17:01, 15 November 2007 (UTC)

Uniflow Rotary Alternative to Piston
By having an exhaust port at the end of the stroke, piston uniflow design needs to recompress residual gas, with some reversibility losses. Furthermore, the recompression pressure makes a substantial restriction to the initial steam flow into the chamber, while the truncated stroke near BDC (bottom dead center) shorten the expansion cycle. New engine concept like the Quasiturbine rotary design allows uniflow, without any of these concerns. Check carefully how Quasiturbine works to understand its uniflow characteristic. —Preceding unsigned comment added by 74.56.253.176 (talk) 14:37, 25 March 2011 (UTC)

Animation speed
As someone new to this topic, trying to understand the operation, I found the animation much to fast to follow what was going on. Do others agree? Might we be able to produce a new one that runs slower, or slow this one down?

Exact numbers
it seems that Skinner Unaflow engines had the highest thermal efficiency of all steam engines. But this article lacks exact numbers of how great efficiency was achieved. Nikolas Ojala (talk) 12:26, 10 July 2013 (UTC)

Spelling?
Is it "uniflow" or "unaflow"...? The attached ref spells it "uniflow". A Google search shows predominantly "uniflow", but some pages have the spelling as "unaflow" Can we get a conformation on which is correct? It's affecting other articles. Thanks - the WOLF  child  22:17, 17 March 2016 (UTC)
 * Technically it's uniflow (diesels too). There is/was a trademark of Skinnner's for Unaflow. Andy Dingley (talk) 22:20, 17 March 2016 (UTC)
 * Thanks... sort of. What spelling should we use? Just one? Or both? And if both, which spelling gets used where? I first became aware of this when the spelling was changed in the infobox for USS Guadalcanal (CVE-60). Thanks again - the WOLF  child  01:22, 18 March 2016 (UTC)


 * If in doubt, uniflow (uncapitalised). "Skinner Unaflow" (capitalised) or "Unaflow" is a term for that one specific marine steam engine, as used on SS Badger and others. Andy Dingley (talk) 07:40, 18 March 2016 (UTC)


 * OK, thanks. - the WOLF  child  07:44, 18 March 2016 (UTC)
