The coal-based and nuclear-based power plants together produce almost half of the world’s energy. Steam turbines are at the heart of these power plants. They convert thermal energy into steam into mechanical energy. This video explains the internal workings of steam turbines and why they build the way they are in a step-by-step logical way.
Type of Material:
Animation (video)
Recommended Uses:
It could be recommended for courses on mechanical engineering topics. Useful for traditional and hybrid/blended teaching.
Technical Requirements:

Content Quality
Rating:
Strengths:
The video presents how a steam turbine works. The video deals with the transformation of thermal energy into mechanical energy by means of a steam turbine. It describes the main parts of a steam turbine: air-foil shapes of the blades, stator and rotor configuration, temperature, pressure and steam velocity evolution. Contents are presented in a clear and concise manner. The contents are core concepts in basic thermodynamics in engineering courses. Information is provided accurately and summarizes well the main ideas.
Concerns:
The material is purely conceptual, without worked examples, practice problems, or interactive elements. It lacks quantitative analysis, limiting opportunities for learners to apply concepts or develop problem-solving skills
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The material could be used for self-learning as well as a supplementary material in traditional or blended/hybrid courses on basic thermodynamics. The learning objectives are clearly stated. Physical phenomena and explanations concerning the work of steam turbines are presented using text, pictures and animations, easy to understand.
Concerns:
Some equations explaining the relation between the main parameters involved in the transformation of thermal energy into mechanical energy should improve the video.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The video is a standalone material, easy to use. Only connection to the Internet and link to the video repository is needed. It can be reproduced in computer, iPad and smartphone. Visual design of the video corresponds to a succession of pictures as the explanations are given.
Concerns:
As corresponds to video materials, limited interactivity.
