Heat Exchangers: Principles, Operation and Design

Since this course aims to deliver only needed and most significant topics for process engineers, there is no need for talking about the necessity of heat transfer. Heat transfer can help you to monitor the temperature change and transfer of heat between different mediums. This lesson is dedicated to:

• One of the heat transfer mechanism called "Conduction"

As you have gone through the first essential heat transfer mechanism, conduction, we can now move on to the second mechanism for heat transfer called "convection". Here in this lecture, you will learn about:

• What is Convection as a Heat Transfer Mechanism and

• How velocity profile is imposed externally on the system, when convection occurs

As you have gone through first two essential heat transfer mechanisms, conduction and convection, we can now move on to third one, called "radiation". This session aims to provide brief information about:

• What is Radiation as a Heat Transfer Mechanism and

• What is Thermal Radiation and its collaboration with Convection

Heat Transfer in practice does not undergo via only one mechanism, instead combination of two or three mechanisms occur in industry. This lesson is to provide practical knowledge about the combination of various heat transfer mechanisms by going over:

• What are the steps/mechanisms in heat-exchanger unit operation;

• How is overall heat transfer rate defined and

• What are the types of flow patterns in heat exchangers

The main heat transfer facilities are heat exchangers which have various types and work with different configurations to attain the desired amount of heat transfer mainly between two or more fluids. In this session, you will learn about:

• Heat transfer mechanism for heat exchangers;

• Various types of them and

• Which type is the most suitable one for industrial utilization and why?

In the previous video, you have learned about different types of heat exchangers and the reason why shell and tube heat exchangers are used more in industry. This lecture will give you brief information about:

• The importance of shell and tube heat exchangers;

• General guidelines about shell and tube sides of the heat exchanger and

• Several flow patterns and appropriate temperature profiles in the equipment

As you have completed the previous session and learned about importance of shell and tube heat exchangers, it would be significant to go over the common applications of this type in industry. Here in this video-lesson, you will learn about:

• Design standards that HX design is based on;

• Advantages of Shell and Tube Heat Exchangers and

• Common Application Areas of Shell and Tube Heat Exchangers

After going over the common applications of shell and tube heat exchangers, we can move on to common internals of this equipment. In this video, you will learn about:

• Internals of Shell and Tube Heat Exchangers;

• Arrangement of baffles and

• Tube Spacing for better heat transfer mechanism

Now it is time to collect what we have already learned: Heat or energy balance and heat exchangers. In this video, you will get into:

• The derivation of heat balance for heat exchangers;

• Example of LMTD calculation and

• Pinch analysis for exchanger networks

You have acquired robust information about heat exchangers, their application areas, and the principle behind how they work. In this video, you will:

• Carefully work on the shell & tube heat exchanger design and learn the sizing principle for heat exchangers;

• Learn about the factors that can affect heat transfer and

• Which configuration for heat exchanger internals can result in higher transfer rates

After looking through the essential steps for heat exchanger design, we can complete the course with effect of fouling and velocity on heat exchanger operation. In this video, you will get valuable knowledge on:

• What is fouling and how it affects the heat transfer rate and

• What is the impact of velocity on heat transfer rate
