Computational Analysis of Heat Transfer Enhancement in a Circular Tubed Heat Exchanger Using Al2O3 Nanofluids | Chapter 7| Engineering Research: Perspectives on Recent Advances Vol. 6

arious heat enhancement techniques are available to find the performance of industrial and practical appliances for a more efficient heat transfer rate. One such method is the use of nanofluids, which has emerged as a passive heat transfer technique in numerous applications. Nanofluids are recognized for their significant potential to enhance heat transfer and are particularly well-suited for use in heat transfer processes. In recent years, extensive research has been conducted to better understand the mechanisms behind heat transfer enhancement and control when utilizing nanofluids. The objective of this work is to study the effect of transfer rate in an annular pipe for water and aluminum oxide nanofluid with 0.25% and 0.5 % by volume for Reynolds numbers 2000 and 3000. A numerical method finite volume was used to observe velocity and temperature. Heat transfer coefficient, Nusselt number and overall heat transfer have been calculated from simulation. The design of the annular tube was done in ANSYS workbench; in which the inner tube was assigned with aluminium and outer tube with copper. It is observed that there is an increased rate of heat transfer when nanofluid of Al₂O₃ with 0.25% compared to 0.5%.

Approximate-analytical Control Volume Method for Solving Boundary Value Problems | Chapter 9 | Fundamental Research and Application of Physical Science Vol. 9

 It is popular that the control volume method is usual in numerical reasoning for solving boundary advantage problems. Using this approach admits obtaining an approximate-analytical design for obtaining a answer to boundary value questions. A method for obtaining numerical mean boundary value questions over the volume being proposed is proposed. The control volume is singular and movable in the field under consideration. The solution of the question is obtained by balancing the differential equation over the book being moved. For two-spatial boundary value questions, it is also urged to average over one variable. On the base of which an common differential is obtained and the resolution of which gives a better resolution to the problem. Examples are given.

Fluid Mechanics Lab Manual | Book Publisher International

The field of research known as fluid mechanics investigates the basic behaviour of fluids in motion or at rest. Whether the fluid is in motion or at rest, it is subject to various forces and environmental circumstances, and it responds to these situations in accordance with its physical characteristics. In several fields, including water resources engineering, hydraulic engineering, environmental engineering, geotechnical engineering, and structural engineering, a basic understanding of fluid mechanics is necessary. The Fluid Mechanics Laboratory actively works to improve civil engineering students' grasp of experimental methodologies, as well as their ability to apply those concepts in real-world settings. The fluid mechanics lab has a variety of flow measurement setups for pipes and channels, including venturimeters, orificemeters, notches, orifices, and mouthpieces, where students may see how the fundamental principles of how the equipment works in action. A lab handbook is required to carry out the laboratory experiments. The current lab handbook gives students an overview of 13 various fluid mechanics laboratory experiments and their real-world applications. The purpose, methods, theory, and equipment needed to conduct experiments are all included in the lab manual, which aids students in creating lab reports. The current lab handbook supports the students not just during experimentation but also during the viva voce portion of the exam.
