Abstract
J. F. Allen and J. Reekie state that the force associated with heat flow in He II has been found to possess two components. When heat flows in a tube containing He II, the liquid which is close to the surface of the capillary is forced to flow in the direction opposite to that of the flow of heat. This is the so-called fountain effect. In the centre of the capillary, however, liquid is forced by the flow of heat to move in the same direction as the heat flow. There is evidence that the fountain effect, that is the surface component, becomes saturated when the heat current is sufficiently high.
