Heat exchangers allow the transfer of heat between two fluids without direct contact. The main types are shell-and-tube, plate, air-cooled, and spiral. Shell-and-tube exchangers consist of tubes in a shell and are the most common, used across many industries. Plate exchangers use corrugated plates clamped together with gaskets to direct fluid flow. Spiral and air-cooled exchangers provide alternatives for applications where fouling is a problem.

Design Considerations for Plate Type Heat ExchangerArun Sarasan
A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. Plate heat exchangers are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers. The small plate heat exchanger has made a great impact in domestic heating and hot-water. Larger commercial versions use gaskets between the plates, whereas smaller versions tend to be brazed.
HEAT EXCHANGERS. Heat exchangers are devices that facilitate the exchange of heat between two fluids that are at different temperature while keeping them from mixing with each other.
2. Double Pipe Heat Exchangers
3. A typical double pipe heat exchanger basically consists of a tube or pipe fixed concentrically inside a larger pipe or tube They are used when flow rates of the fluids and the heat duty are small (less than 5 kW) These are simple to construct, but may require a lot of physical space to achieve the desired heat transfer area.
4. Double-pipe exchangers is the generic term covering a range of jacketed 'U' tube exchangers normally operating in countercurrent flow of two types which is true double pipes and multitubular hairpins. One fluid flows through the smaller pipe while the other fluid flows through the annular space between the two pipes. Two types of flow arrangement: Parallel flow Counter flow
5. • The fluids may be separated by a plane wall but more commonly by a concentric tube (double pipe) arrangement shown in fig. If both the fluids move in the same direction, the arrangement is called a parallel flow type. In the counter flow arrangement the fluids move in parallel but opposite directions. In a double pipe heat exchanger, either the hot or cold fluid occupies the annular space and the other fluid moves through the inner pipe. The method of solving the problem using logarithmic mean temperature difference is typical and more iteration must be done. So it takes more time for the problem to solve. Therefore another method is practiced for solving this type of problems. This method is known as Effectiveness and Number of Transfer Units or simply ε-NTU method.“Effectiveness of heat exchangers is defined as actual heat transfer rate by maximum possible heat transfer rate”.The LMTD method may be applied to design problems for which the fluid flow rates and inlet temperatures, as well as a desired outlet temperature, are prescribed.
6. Application of Double Pipe Heat Exchanger Pasteurization or sterilization of food and bioproducts Condensers and evaporators of air conditioners Radiators for internal combustion engines Charge air coolers and intercoolers for cooling supercharged engine intake air of diesel engines.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

6. Double Pipe Simplest type has one tube inside another - inner tube may have longitudinal fins on the outside However, most have a number of tubes in the outer tube - can have very many tubes thus becoming a shell-and-tube
8. Shell-and-Tube Heat Exchangers are the most important type of HE. It is used in almost every type of industry. This type of heat exchanger consists of a set of tubes in a container called a shell. The fluid flowing inside the tubes is called the tube side fluid and the fluid flowing on the outside of the tubes is the shell side fluid.
10. Some common heat-exchanger terms Tube side: Inside the tubes. Shell side: Outside the tubes, between the tubes and the shell. Tube sheet A thick plate provided with holes (one per tube) in which the tubes are fixed. Tube bundle Consists of tubes, tube sheet and baffle plates Shell A cylinder of plate in which the tube bundle is placed
13. Shell and Tube Heat Exchangers Construction Fixed Tube-sheet type U-tube type Floating Head type
14. Front head type A-type B-type B A Channel and removable cover Bonnet (integral cover)
15. Shell type E-type F shell Longitudinal baffle F E One-pass shell Two-pass shell
16. More shell types G and H shells normally only used for horizontal thermosyphon reboilers J and X shells if allowable pressure drop can not be achieved in an E shell G H Longitudinal baffles Split flow Double split flow J X Divided flow Cross flow
17. Low-finned Tubes Flat end to go into tube sheet and intermediate flat portions for baffle locations Available in variety of metals including stainless steel, titanium and inconels
18. Plate and frame Plates hung vertically and clamped in a press or frame. Gaskets direct the streams between alternate plates and prevent external leakage Plates made of stainless steel or higher quality material Plates corrugated to give points of support and increase heat transfer
27. Spiral Heat Exchangers Spiral heat exchangers can be used in most applications in the chemical process industry In many difficult applications where fouling and plugging are problems, a standard shell and tube design may not be effective While a spiral heat exchanger often has a higher initial cost, it may provide a lower life cycle cost due to lower fouling rates and ease of maintenance
28. A spiral heat exchanger is composed of two long, flat plates wrapped around a mandrel or center tube, creating two concentric spiral channels In a spiral heat exchanger, the hot fluid flows into the center of the unit and spirals outward toward the outer plates while at the same time, the cold fluid enters the periphery and spiral inward, exiting at the center
