Pondicherry University signed/inked a Memorandum of Understanding (MOU) with the Center for Mathematical Modeling and Computer Simulation

The Pondicherry University on Monday signed a Memorandum of Understanding (MOU) with the center for Mathematical Modeling and Computer Simulation (C-MMACS) for setting up a carbon dioxide monitoring station at the university campus.

C-MMACS is a unit of Council for Scientific and Industrial Research (CSIR) located at Belur, Bangalore. The monitoring station at the university is being funded by the Department of Science and Technology, New Delhi.

The CO2 monitoring station will be a national facility for studying the impact of green house gases on global climate particularly related to India. The station will collect the air flowing from the land and also from the sea in different seasons depending on the direction of the wind blowing in the area. The data generated will be utilized by both the university and C-MMACS for research and analysis.

The facility will be part of a global network of similar monitoring stations. The university will provide all infrastructural support for the facility.

Vice- Chancellor of Pondicherry University Mr J A K Tareen said that the MOU signals the “University’s entry into a new era of advanced research in both basic and social science.” He said that the university cannot grow in isolation and such interaction with premier institutions such as CSIR C-MMACS will help achieve its vision. He also said that the university in its 25th year has now become the fastest growing central university in the country and has recruited more than 175 teaching staff in the last two years. Dr A R Upadhya, Sc-Incharge of C-MMACS, made a presentation about the organization and its contribution to civilian airspace technology in the country, Dr N.K. Indira, scientist,CMMACS and project coordinator was also present.

Aerodynamic Drag Reduction of Bluff Bodies
Application of Natural Ventilation

 



By Gargeshwari Suryanarayana
Gargeshwari  K Suryanarayan, Ph.D: Studied Aerospace Engineering at Indian Institute Science, Bangalore, Scientist at National Aerospace Laboratories, Bangalore, India
Received many citations based on publications in Experiments in Fluids, Journal of Visualization, AIAA and IUTAM Conferences Honorary, Advisor, DAAD, Bonn.

 

Aerodynamics of bluff bodies has gained the attention of aerodynamicists all over the world in recent times, primarily because of importance given to drag reduction by the automobile industry. Since pressure drag accounts for bulk of the drag of bluff bodies, any technique to manipulate and control the overall pressure field around such bodies to achieve base pressure rise causes reduction of drag.

Interestingly, not many works are found on 3 - dimensional bluff bodies such as spheres. Currently, interest in spherical airships is growing triggered by the tourism industry. However, the high drag and management of highly unsteady wake of spheres are some of the aerodynamic issues that need to be addressed. This book offers the concept of passive natural ventilation as a potential solution. Natural ventilation occurs when the stagnation zone and the base are interconnected through an internal duct, which causes a jet flow through the center. Based on several years of experimental research, it is shown that natural ventilation of a sphere leads to substantial drag reduction and reduced wake unsteadiness at high Reynolds numbers.

51st NAL Foundation Day

Another successful year gone by……...., Dr. M.N. Satyanarayana, Jt Head, KTMD ,began by  reminiscing  the achievements of the past directors and colleagues who made a difference to NAL, on the occasion of the 51st NAL foundation  celebrated on 3 September 2010 at the SR Valluri auditorium . Dr. Sajeer Ahmed, Adviser M&A welcomed everyone and introduced the speakers Dr. PV Acharya, Director C- Dot and Dr. V Arun Kumar, Head, Propulsion Division who gave the 11th Technology lecture. Dr. PV Acharya in his talk on “Broadband -Technology and its Impact on India.” defined Broadband in India and abroad. Broadband in India is connectivity at 256kbps, a fundamental right according to Dr. Acharya, is essential for economic growth, infinite possibilities for a nation of billion people, with urban India developing at a fast pace, providing broadband access is one of the strategic objectives for government worldwide. It is essential for the 70% rural Indian population. The way ahead is with the Government creating the National Broadband Network (NBN) through which e-governance will be delivered. Dr. Acharya enlightened the audience about the various International Broadband initiatives  such as SWAN – State Wide Area Networks at Rs 3300 crores to connect State HQ’s to Block HQ’s through District HQ’s,2 Mbps intrastate network for rolling out various MMP’s, CSC – Common Service Centre 5700 crores, NKN – National Knowledge Network @ 6800 crores and the Panchayat Network @ 1800 crores.

Dr. V Arun Kumar, Scientist, Propulsion Division in his lecture on “Advanced Bearing Technologies – Magnetic & Foil Bearings” educated the audience through the various types of bearings, their advantages and disadvantages, the future of the bearings, and NAL’s pioneering work in this field.

Dr. AR Upadhya, Director, NAL in his Presidential remarks embarked on the contribution of Late Dr. P Neelakantan, the bearing technology to be inducted this month, the RTA program and expected the first flight to take off to the skies in 2016-17. He thanked Dr. P V Acharya and Dr. Arun Kumar for the knowledge imparted to the august audience. The Annual report and “Golden Memoirs” published on the occasion of NAL’s Golden Jubilee Celebrations was released on this occasion. Dr. Acharya distributed the NAL foundation awards   to the employees and the children of NAL Employees who have excelled in Studies and Extra-curricular activities for the year 2010. The awardees were given a Certificate with a cash prize. Dr. Ranjan Moodithaya, Head ATF & KTMD presented the vote of thanks.
