This course serves as a springboard into Engineering Thermodynamics for new students or as a refresher for students already familiar with some of the concepts and are looking for somewhere to brush up the fundamentals.
The course covers a broad spectrum of common topics that are applicable to a wide variety of situations in numerous engineering sectors;
All of these topics are fascinating and are around the A-level to University level in terms of technical content... but don't worry! We cover these topics in a logical order and start off simple so that we do not lose you along the way. Most videos follow the format of a discussion of the theory and then we go through a worked example. We then recommend that students have a go at the practice questions that accompany most videos so that you can put your skills to the test. There are full worked solutions so you are able to check how you perform.
We at Learn-Ed believe that the format of "Theory - Worked example - Have a go for your self" is one of the best methods of learning - particularly the "Have a go for yourself" element.
We also try to describe various applications that each theory has to help give context as to why its interesting to learn about.
We hope to see you in our lessons!
This video introduces some common terms used in thermodynamics to the student: Fluid, Temperature, Viscosity, Density, Pressure and Gravity.
This video discusses pressure in more detail than the definitions video aswell as a powerful equation that links pressure with depth for incompressible fluids. This video also describes basic hydraulic theory.
This video takes the theory within the fluid pressure video to look at Buoyancy and Archimedes Principle.
This video introduces the three main regimes of fluid flow; Laminar, Transitional and Turbulent flow. It also describes how we can determine what fluid flow regime we might have for a given scenario.
This video brings viscosity into fluid flow theory showing how we obtain velocity profiles when fluid flows over static objects. This video also looks at Poiseulles Law and the parameters that define the flow rate when the law is applicable..
This video starts off by describing energy and its associated laws. Then we look at something called Bernoulli's equation which is powerful equation to compare the different forms of energy in one fluid stream.
This video looks at the concepts of lift and drag over an aerofoil as well as drag on simple geometries.
This video introduces combustion and common terms linked to the chemical reaction then demonstrates how to solve problem on the stoichiometric combustion of Methane.
This video builds upon the definitions in an earlier video but focuses on terms that are associated with thermodynamics cycles. Further, the video describes an equation that links pressure, temperature and volume.
This video provides insight as to what irreversibilities are and why we use reversible processes to model power cycles. We then discuss arguably the most important power cycle - The Carnot Cycle - and why it is so important.
This video goes into depth on some of the core components to an internal combustion engine, specifically those that form the combustion chamber. We then talk about the Otto cycle which is one that suitably model spark ignition engines.
This video looks at a new cycle - The Diesel Cycle. As the name suggests, this cycle models engines that operate on diesel or in engineering terms - compression ignition engines. We also look at some of the core differences this cycle has with the Otto cycle.
This video discusses the Stirling cycle which is in general a topic merely for academic interest. There are some interesting benefits to Stirling engines and we can even looks at one in action!
