CFD Simulation of Compact Type Mini Channel Heat Exchanger by Using of Water

Abstract—A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In the conventional heat exchangers, pipes are larger in size which makes heat exchanger bulky. But in some typical applications such as closed loop gas turbine heat exchangers, cryogenic applications, heat exchangers used in PWR power plants, nuclear submarines, etc., size and weight are critical design constraints on the heat exchanger. Also for high pressure applications tubes are subjected to high bending stresses. To overcome these difficulties, compact heat exchangers can be employed. Mini channels heat exchanger is a type of compact heat exchanger in which mini channels are machined on metal plates and then such plates are bonded together. Such an arrangement provides high strength so that it can be used for high pressure applications. It has been observed that in mini channels, convective heat transfer coefficient is more than the tubes used in conventional heat exchangers. Hence, the length for same heat transfer is greatly reduced which results in reduced overall size and weight of the heat exchanger. Electronic device are in heavy demand for computer processor applications and generate large amount of heat. These high power device can be cooled off very effectively by either liquid or gas coolant flowing through micro or mini channels. Continuous research work is ongoing for developing high speed processor which generate high amount of heat. Cooling of such particular systems requires high amount of mass flow rate and compactness is also required. In present work, a mini channel heat exchanger is designed with assuming inlet and outlet of hot temperature, inlet of cold water temperature and also the mass flow rates of cold and hot water. This compact heat exchanger can be used for cooling purpose of electronics device like silicon chip which would be used for microprocessor. In order to cool down silicon chip, it is kept in place of hot fluid plate. Cooling of silicon chip is required to prevent from damage and subsequently failure. The heat exchanger is designed for obtaining 10°C of hot fluid.

IJSRD is an India’s leading open access e-journal for all kinds of science, engineering & technologies manuscript. We publish original and high quality papers.

International Journal for Scientific Research & Development (IJSRD) is one of the leading e-journals which offers new ideas of current trends in Engineering and Science through published research papers with authentic data and pure knowledge. This online journal in the internet space is made available for all interested research scholars who look forward to showcase and share their work with their peer groups and others working in the same space across the globe.

At IJSRD, an exhaustive list of executive board members is available who were invited from a wide range of colleges, universities and research organizations to supervise the content. This online journal has proven to be extremely helpful for scholars and research students who call for research papers in their undergraduate, post graduate and higher levels of education. The original and supreme quality research papers that are uploaded and submitted in IJSRD are aimed at providing an outstanding all-round development to the students and research scholars in the field of Engineering and Technologies.

IJSRD is a monthly journal, publishes one issue per month. The precise and analytical narration of knowledge given by the reviewers in the journals make them more credible.IJSRD, touted as one of the premium online destinations for Journal of Science, has received about 3,424 papers and has about 5109 authors. The total number of accepted papers is 1196 till date.

IJSRD is easy to use and an open access peer reviewed International Journal wherein the research scholars are given the opportunity of downloading any relevant article or research paper from the website free of cost. These scholars are also allowed to submit their research papers online and generate an e-certificate online at any given point of time. One of the major highlights is that of referring to the statistics for each of the authored articles and papers and checking the status of the paper submitted online.

#Ijsrd : Influence of Metal Temperature on Strength of Rolled Steel Product

#Ijsrd :
Influence of Metal Temperature on Strength of Rolled Steel Product

Abstract—Rolling is extensively used metal forming process. Almost 90% of cast iron or steel products pass through rolling process at least once in its life cycle. Rolling products are most extensively used in daily life. Use of these products can be seen in bridges, towers, leaf springs, boilers, constructional structural parts and also in daily life products like knives pipes etc. In today’s era, quality of products is one of most important factor considered for its use. Quality of a product can either be controlled or improved by changing in composition or by using heat treatment processes.  In rolling products composition is not only the factor which improve the quality of product but temperature plays a vital role in maintaining and improving quality. By changing temperature of rolling we can change grain structure and its mechanical properties without changing its composition.

#IJSRD An Automatic CAN or Plastic Bottle Crusher Machine

An Automatic CAN or Plastic Bottle Crusher Machine

Abstract :

Crushers are major size reduction equipment used in mechanical and allied industries which crushes different types of soft and hard materials. The can or bottle crusher machine is widely used in beverage industries or in scrap dealers shop (Bhangarwala) to reduce the volume of the cans/bottles solely to increase the transportation volume and thus to reduce the transportation cost. Hence in this design and analysis of various parts are necessary. This paper focuses on review of a work carried out by researchers on analysis and design of various parts due to which the design quality of that parts will be improved. There are so many researchers who have done work on design and analysis, but still there are so many areas of scope regarding this design and analysis. The Electric Motor and a microcontroller make up the backbone for this project. Overall, this project involves processes like design, fabrication and assembling procedures. Even though there are many types of the can crusher machine in the market, the completion of this new model provides a more practical usage than previous one.
