Analysis of Transient Flow and Heat Transfer in a Vertical Inverted U– Tube Steam Generator

N. A. Shahid, M. O. Ahmad, M. Mushtaq, S. Nazir


A mathematical model of a vertical inverted U–tube steam generator (UTSG) is used to analyze the transient flow and heat transfer in it. To simulate the transients, the mathematical model is discretised in time and space coordinates. For the solution of this one dimensional heat problem, a finite differences numerical simulation technique is employed in order to find the temperature distribution of primary and secondary fluids. An optimum boiling length of the tube is also obtained. For further analysis, the temperature distribution profiles of secondary and primary fluids are drawn at specified intervals of time.
