Abstract

Condensing flows in nozzles and fixed blades of steam turbine have always been the subject of many studies.In such flows, existence of liquid phase in vapor changes the nature of the flow. The major of changes are due to four main mechanisms included nucleation, droplet growth, coalescence and breakage of droplets. In this paper,the effects of coalescence process between droplets have been investigated in a condensing flow in convergent-divergent nozzle in one dimensional form
