Turbomachinery Educational Programs


SoftInWay presents new course Steam Turbine Fundamentals for mechanical engineers aspiring to enhance their understanding of steam turbine basics and find new, more accurate, and cost-saving technical solutions.

The highlights of the program include the fundamentals of thermodynamics, gas dynamics, structural analysis and basics of steam turbines and their elements. This comprehensive course gives an in-depth insight into turbine engineering, starting from general data like turbine classification and layouts, and ending with tertiary components design.

By the end of the course, the participants will have the knowledge to successfully carry out steam turbine design and operation tasks.


“A most useful and interesting educational course backed up by excellent course text with helpful examples. The course content covered all of the basic steam turbine fundamentals and was delivered at a pace that allowed the information to be digested ensuring a full understanding. The lecturers were extremely helpful and were more than willing to answer any questions. Overall a very good insight into steam turbine fundamentals."
