Karnataka State Centre has instituted a Memorial Lecture in the name of Prof. B.R. Narayana Iyengar, an outstanding Mechanical Engineer, illustrious Academician, a reputed Teacher, Design Engineer and Past President of The Institution of Engineers (India).

This year's Memorial Lecture was delivered by Dr. S. Paul Vizhian, Professor, Department of stMechanical Engineering, University Visvesvaraya College of Engineering on 31 January 2017. He

spoke on “Experimental and Computational Analysis to predict the endurance Life of Compact Heat Exchangers”. Er. Jasmail Singh, Hon. Secretary welcomed the invitees, members and the engineering students present and also introduced the Speaker.

Dr. A. S. Kodanda Pani briefed the invitees about the achievements of Prof. Narayana Iyengar. Prof. Iyengar was a first rank degree holder from UVCE. Later, he became the Principal of the same college. He was the Chairman of the State Centre during 1972-74 and was elected as the President of IEI during 1986-87.

Dr. Paul Vizhian briefed about the necessity to estimate the life of any component for its flawless performance for the designed life of any system. Compact heat exchangers (CHE) are being utilized in advance technology development programs like hypersonic ram jet engines, laser weapons, air craft infrared suppressor and large high efficiency gas turbines. But there is no information available from the open literature on the experimental procedure for endurance life estimation of CHE being used in aircraft. The experimental test procedure is formulated based on MIL standard as per the data collected during the real flight conditions. As the test procedure is very expensive, computational method has been formulated to reduce the cost and time of analysis.

Computational method is used for real life complicated problems. The estimation of the endurance life of CHE is carried out using CFD. Hence the fatigue endurance life, is found to be very high around about 60 times more than the theoretical estimation, This leads to estimation of creep endurance life of CHE.

The Speaker concluded saying that creep life is found to be the major factor for failure of the CHE. The method formulated can be successfully used to estimate the endurance life of the CHE.

Dr. N. Chikkanna, Chairman in his presidential remarks paid rich tributes to Prof. B. R. Narayana Iyengar for his contribution to engineering education and to the Institution. He also thanked the Speaker for the enlightening technical presentation made by him on “Compact Heat Exchangers”.

member and Convener of the program introduced the subject.

Dr. Kodanda Pani in his address said, Bengaluru was called as a

Garden City and a City with salubrious climate. Maharajas of

Mysore with their able Dewans developed Bangalore on a

planned basis. At present, the City is facing acute traffic

congestion, garbage everywhere, sewage in storm water drains

and lakes, pot holes on roads everywhere, etc.

Dr. B. T. Lalitha Naik in her presentation started with the

selection of the site for Bengaluru by Kempe Gowda-I in the year

1537, and subsequent development by Kempe Gowda II in 1585.

He got towers erected in four corners of Bengaluru anticipating

extension of Bangalore upto those points. Bengaluru attracted

rulers of other parts of India like; Vijaynagar Empire. Kempe

Gowda IV established Bengaluru as a commercial center, gave

importance for citizen care, housing, etc: Dharmanbudhi Tank,

Halasuru Tank, Karanjikere, etc were built, avenue trees were

provided. Further development was during the Chikkadevaraja

Wodeyar's period supported by good Dewans and Ministers.

Hyder Ali and Tippu Sultan developed Lalbagh Park, Tippu Sultan

Palace, etc. Dewan Poonayya improved Bengaluru after Tippu's
