This breakthrough of researchers at IIT Madras and Khalifa University in mini-channel heat exchangers has been published in the reputed peer-reviewed journal Applied Thermal Engineering (https://doi.org/10.1016/j.applthermaleng.2023.121064).

Second space age

India’s second Space Age has been driven by impressive technological innovations and the miniaturization of electronic components, enabling advanced functionalities, exemplified by the ongoing Chandrayaan-3 mission, say sources from IIT Madras.

High-performance computing processors can generate up to 200-250 W or more of power, resulting in heat loads of up to 1 kW, necessitating efficient heat management. Liquid-cooling systems, especially micro/mini-channel heat sinks, are considered best suited for dissipating heat in such systems.

The research conducted by the IIT Madras team aims to disrupt the smooth flow inside the mini-channels through the use of plate electrodes.

Significance

Elaborating about the significance of this research, Prof. S. Vengadesan, Department of Applied Mechanics and Biomedical Engineering, IIT Madras, said, “The new design developed by this research team uses thin plate electrodes that introduce swirling flows inside mini-channel fluids, which result in the formation of vortices at the boundaries, which in turn facilitates better heat transfer.”

Design

To validate the design, the researchers employed computational methods that simulate fluid flows in three dimensions.

Through these simulations, they observed how the chaotic swirling flows effectively disrupted the smooth flow at the walls of the channels, and thereby enhanced heat transfer, say sources from IIT Madras.

The electrodes induce vortices at the boundary layer due to the Onsager-Wien effect, and disrupts the smooth flow, say sources from IIT Madras.

The study’s applications in electronic thermal management, particularly in space technology, are vast. Additionally, the electrically driven flow vortices generated by this design eliminate the need for additional geometrical modifications.

With no moving parts, this design operates without vibration and requires no maintenance. Furthermore, its electrically operated nature ensures intelligent control and quick response, say sources from IIT Madras.

The Institute offers undergraduate and postgraduate programmes leading to B.Tech., M.Sc., M.B.A., M.Tech., M.S., and Ph.D., degrees in a variety of specialisations.

IITM is a residential institute with more than 600 faculty and 9,500 students. Students from 18 countries are enrolled here. IITM fosters an active entrepreneurial culture with strong curricular support and through the IITM Incubation Cell.

Recognized as an Institution of Eminence (IoE) in 2019, IITM has been ranked No.1 in the ‘Overall’ Category for the fourth consecutive year in India Ranking 2022 released by National Institutional Ranking Framework, Ministry of Education, Govt. of India.

The Institute has also been ranked No.1 in the ‘Engineering Institutions’ category in the same Rankings for seven consecutive years – from 2016 to 2022.

It was also adjudged as the ‘Top innovative Institution’ in the country in Atal Ranking of Institutions on Innovation Achievements (ARIIA) in 2019, 2020 and 2021.

ARIIA Ranking was launched by the Innovation Cell of Ministry of Education.

The schedule to submit applications for JEE Advanced 2025 has been announced along with that of AAT 2025 registration,

Application process for AAT starts after result declaration of JEE Advanced. This year too, the trend is no different.

Who will conduct AAT 2025?

AAT 2025 will be conducted by IIT Kanpur and is expected to see a participation in impressive numbers. The same institution is conducting JEE Advanced 2025.

Details about the exam are available on the official website mentioned above. Students who pass AAT 2025 will be able to study BArch in IIT Roorkee, IIT Kharagpur and IIT (BHU) Varnasi.

Who can take up AAT 2025 registration?

Students who have passed JEE Advanced 2025 with required qualifying marks can take up AAT 2025 registration. Applying for JEE Advanced requires a pass in JEE Mains.

Candidates who have passed plus two with maths, physics and chemistry as subjects will be able to take up JEE Mains registration. The process to take up JEE Advanced AAT 2025 registration is online.

1. The URL has to be typed into the browser and the webpage has to be allowed to download.

2. Once the website is available, students should click the link for JEE Advanced AAT 2025 registration and enter JEE Advanced 2025 registration number, their date of birth, mobile number and email address.

3. Post providing the above details, applicants will be asked if they are interested in AAT. Students have to answer ‘Yes’ to take up JEE Advanced AAT 2025 registration.

4. Candidates have to provide the required information and choose the centers where they wish to write the exam and submit the form.

5. They will receive message indicating successful completion of JEE Advanced AAT 2025 registration.

The message has to be downloaded and a printout of it has to be taken and preserved for use in future. This could be of use during the admission process.

Website for JEE Advanced 2025/AAT 2025 Registration is Here

Exam pattern

Candidates who have completed JEE Advanced AAT 2025 registration must also know the exam pattern if they are to score good marks.

Those who have taken up AAT 2025 registration can take up the exam which will be held in offline mode, as a pen and paper mode test.

Candidates will have three hours time to answer all the questions. The medium of the test is English.

The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

Syllabus for AAT 2025

The next thing to do after completing AAT 2025 registration is focus on preparing for the test.

The subjects to be studied while preparing for AAT 2025 are mentioned below. Candidates can also refer the official website for more information on syllabus when the registration for the exam begins:

Geometrical Drawing

Exercises in geometrical drawing containing lines, angles, triangles, quadrilaterals, polygons, circles, etc. Study of plan (top view), elevation (front or side views) of simple solid objects like prisms, cones, cylinders, cubes, splayed surface holders, etc.

Freehand Drawing

This would comprise of simple drawing depicting the total object in its right form and proportion, surface texture, relative location and details of its component parts in appropriate scale.

Common domestic or day-to-day life usable objects like furniture, equipment, etc., from memory.

Three dimension perception

Understanding and appreciation of three-dimensional forms with building elements, colour, volume and orientation. Visualization through structuring objects in memory.

Architectural Awareness

General interest and awareness of famous architectural creations – both national and international, places and personalities (architects, designers, etc.) in the related domain.

Imagination and Aesthetic Sensitivity

Composition exercise with given elements. Context mapping.

Creativity check through innovative uncommon test with familiar objects. Sense of colour grouping or application.

The medium of the test is English. The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

The admit cards obtained for JEE Advanced 2025 can also be used to gain entry into the test centers for AAT 2024.

Point to remember

Candidates can visit the official website of JEE Advanced exam for more information on JEE Advanced AAT 2025 registration and other related topics.

The students have to quickly take up the AAT 2025 registration as the time left would be very short.

Like JEE Advanced exam where the registration is open for a longer duration, that of AAT 2025 registration is open for only a short period.
