The International Institute of Information Technology Pune will be conducting SONIC 07 ,a national level symposium on Computational Fluid Dynamics .The event is being conducted for the second time in succession after the resounding success of Sonic 06 , The event will encompass a wide range of topics related to CFD. The purpose of symposium is to bring Industry and Academia together to share their expertise. We invite technical papers on following topics. Aerospace, Automotive, Thermal, Hydraulics and Pneumatics, Hydrodynamics, instabilities and turbulence, Aero-Acoustics Bio-medical Food processing, Multi phase flows,Environmental, Combustion and Reacting flows, Grid generation, High performance computing / Parallel Computing. The papers should be strictly related to CFD. Participant/s can be any Professional in the field of CFD, academic scholars and Graduate/Post Graduate students. The competition will be held where the selected participants will get an opportunity to present their ideas and prizes will be awarded for the best paper.
