A study of nucleating and wet steam flows in turbines

SYNOPSIS This paper describes a study in which nucleation theory has been applied to the flow in turbines.The treatment is one dimensional and use is made of friction coefficients to allow for the aerodynamic losses. The experimental results quoted have been obtained independently from tests on a model turbine. The results of a dry run have been used to obtain friction coefficients which have then been adopted in the prediction of the wet test.The theoretical results are extracts from the computer prints out, the comparisons are with the turbine wet efficiency and the agreement obtained is remarkably good.
