7 Myths of Heat Transfer Rolls Maxcess Americas

In a partially filled heat transfer roll, gravity pulls fluid to the bottom of the roll where spiral channels can push the fluid like an auger. In a properly filled roll with the air bled off, the spiral channels have no effect on the fluid inside as the roll turns. Think of a double wall heat transfer roll as a

Spiral Orbit Tribometry I. Description of the Tribometer

Referring to Fig.2, the spiral can be described as the result of a nonzero i component of w. This component moves the locus of contact on the ball off the great circle it would have if the orbit was a perfect circle and instead generates a spiral on the ball as it rolls in its spiral orbit. This has the
