Experiments have been carried in an adiabatic small-aspect-ratio pipe and the fluids involved are isoviscous. Inclined configuration has been studied for the first time in this research. There has also been observed a novel asymmetric behavior in the flow which has never been observed before in the isothermal limit in which the cold finger appears to advance faster than the hot one. complementary experiments have been done to clarify this asymmetric behavior is associated with the wall contact and the formation of a warm less-viscous film of the fluid lubricating the cold moreviscous finger along the pipe. On the other side of the pipe, a cool more-viscous film forms decelerating the hot less-viscous finger. The asymmetric behavior of the flow is finally quantified over the full range of experiments carried.application/pdfengThe author of this work is the copyright owner.
