Natural Circulation - an overview | ScienceDirect Topi

Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3.Heat is applied to one leg, called the raiser tube, where the water–steam mixture flows upward.
