摘要

In a tube-in-shell heat exchanger, hot fluid flows through a bank of parallel tubes immersed in a constantly renewed cold bath. As the hot fluid advances through the tubes, it cools. We would like to determine its temperature as a function of the distance it has traveled. In some fluids (e.g., water) longitudinal heat conduction can be neglected compared with longitudinal convection. But in helium-II, it cannot. Here, ''it'' refers not to ordinary heat conduction, but to heat conduction by the vastly more powerful Gorter-Mellink counterflow. So the temperature distribution in the tubes is determined by the interplay of longitudinal convection, longitudinal Gorter-Mellink counterflow, and transverse heat transport through the walls.
