Thermal engineering training videos
Learn Engineering comprises of a small team of engineers and animators located in India (the current team size is 4), with a mission of creating high quality, free engineering videos for the world. They aim to create videos on all of the main topics of engineering. This video playlist covers the topic of Thermal Engineering.
How does your Air-conditioner work?
Air conditioners give you the much needed thermal comfort during scorching summer. More specifically, air conditioners help to maintain the room temperature at optimum level, as well as removing airborne particles and humidity from the room. Let’s find out how these devices work.
Understanding the Second Law of Thermodynamics
The ‘Second Law of Thermodynamics’ is a fundamental law of nature, unarguably one of the most valuable discoveries of mankind; however, this law is slightly confusing for most engineers or students. The main reason for this is because it has so many complex terms in it and that there are many ways that this second law can be stated, but most importantly, many do not understand what are the applications of this law is. In this video we will create a real physical insight into this law with a minimum use of mathematics.
How does a Refrigerator work?
Have you ever wondered how the refrigerators in your home work? Refrigerators have become an integral part of every household. Beginning with a basic refrigerator model, this video will elaborate on the operation of modern refrigerators, along with the secrets behind their high energy efficiency.
How does a Steam Turbine work?
Nuclear and coal based thermal power plants produce almost half of the world’s power. Steam turbines lie at the heart of these power plants. They convert thermal energy in the steam to mechanical energy. This video will explain the inner workings of the steam turbines and why they are constructed the way they are.
How does a Boiler work?
A detailed analysis of a typical power plant boiler is illustrated in this video. Working and construction details of water tube boilers are explained. Different parts of the boiler such as the economiser, super heater, re-heater, water wall and steam drum are illustrated. This video also explains an important concept during the boiler heat addition process.
How does a Thermal Power Plant work?
The operation of a thermal power plant is explained, starting with an overview of the Rankine cycle. Topics such as the Generator, Steam turbine, condenser, feed water pump and the boiler are discussed. The basic Rankine cycle is modified and the use of super hearing, reheating and feed water heating (deaerator) is explained thereafter.
Refrigerator working – The Basics
How a Refrigerator works and the refrigeration principle behind it is explained in this video. The concept of the Vapour compression cycle, throttling & C.O.P, the use of evaporators, condensers and compressors are also explained in this video.
