This volume contains the proceedings of the Workshop on In stability, Transition and Turbulence, sponsored by the Institute for Computer Applications in Science and Engineering (ICASE) and the NASA Langley Research Center (LaRC), during July 8 to August 2, 1991. This is the second workshop in the series on the subject. The first was held in 1989, and its proceedings were published by Springer-Verlag under the title "Instability and Transition" edited by M. Y. Hussaini and R. G. Voigt. The objectives of these work shops are to i) expose the academic community to current technologically im portant issues of transition and turbulence in shear flows over the entire speed range, ii) acquaint the academic community with the unique combination of theoretical, computational and experimental capabilities at LaRC and foster interaction with these capabilities, and iii) accelerate progress in elucidating the fundamental phenomena of transition and turbulence, leading to improved transition and turbulence modeling in design methodologies. The research areas covered in these proceedings include receptiv ity and roughness, nonlinear theories of transition, numerical simu lation of spatially evolving flows, modelling of transitional and fully turbulent flows as well as some experiments on instability and tran sition. In addition a one-day mini-symposium was held to discuss 1 recent and planned experiments on turbulent flow over a backward facing step.

Instability, Transition, and Turbulence

How And Why In Basic Mechanics

Dr. S.N. Sewak 

his highly acclaimed book brings out the long struggle of Dr. Binayak Sen in the fields of health care and protection of human rights. Dr. Sen slogged for the poor tribals in Chhattisgarh. The state government considers him an enemy and has charged him with sedition. The people of that region consider him their best friend. As a doctor, he has brought relief to thousands of men, women, and children. As the Secretary of the People's Union for Civil Liberties (PUCL), he has exposed the atrocities of the police and state-sponsored peace force, Salwa Judum, against the innocent masses. These machinations were designed to displace those poor people from their habitat. The idea was to enable the influential corporate firms to tap the mineral wealth of that region. The noble doctor has been dubbed as “Maoist Courier” and convicted on flimsy grounds. Nevertheless, he has also been honoured with international awards in the USA and South Korea for his work. The government of Chhattisgarh continues to pursue baseless cases against him. This book presents the noble doctor in true perspective and tries to present the truth before the entire world. It proves that Dr. Sen is a friend and not an enemy of the masses. This book was written after a lot of research. The authors opine that Dr. Binayak Sen's acquittal might herald a new era in India. Read this book to welcome that era…
