INTRODUCTON    TO THERMODYANAMICS

onlıne  course

Welcome to “Introduction to Thermodynamics”!

Welcome, Everyone!

This course will introduce the core concepts necessary to understand energy transfer. We will focus on large scale power systems, such as the power plants that provide stationary power around the world, as well as small scale systems, like cell phones and microprocessors. The goal of this class is to provide you with the skills to analyze systems by identifying the relevant mechanisms of energy transfer and by quantifying the system characteristics. To build these skills, we will progress through the conservation principles of mass and energy, and thermodynamic state relations. We will then consider basic power, refrigeration, and heat pump cycles, and we will evaluate some alternative and renewable energy carriers.

Energy is one of the most important challenges we face in our global society. This course material is the tip of the iceberg. I hope the content plants a seed of interest and passion to pursue these topics further in your professional careers and in your day-to-day activities. At the end of this class, I hope you will thoughtfully consider the energy decisions you make every day and that you will imagine new and better ways to use energy around the world.

Welcome and enjoy!

Questions about the Accompanying Lab Course

In this course, you will learn how to characterize the energy state of a system and the mechanisms for transferring energy from one system to another. These are the tools necessary to understand stationary and transportation power systems from small scale, like batteries, to large scale, like nuclear power plants.

 

This course will provide you with an introduction to the most powerful engineering principles you will ever learn: thermodynamics! Or the science of transferring energy from one place or form to another place or form.  We will introduce the tools you need to analyze energy systems from solar panels, to engines, to insulated coffee mugs.

 

More specifically, we will cover the topics of mass and energy conservation principles; first law analysis of control mass and control volume systems; properties and behavior of pure substances; and applications to thermodynamic systems operating at steady state conditions.
