Title	:	Comparison Of Bowman And Ronald Lmtd Correction Charts
Country	:	India
Authors	:	Saggarla Murali

Abstract:Mean Temperature Difference is a key factor for accurate design of shell and Tube Heat Exchangers. However, Accuracy of this depends on method by which it has been evaluated. Numerous Investigations have contributed analysis of the mean temperature difference for Heat Exchangers and presented them in the form of equations and Charts. When making heat exchanger calculations, Engineers generally rely on correction Charts. Perhaps, these charts on plain paper are not suitable for Automated Design, accurate reading is difficult and time consuming. This limitation can be greatly reduced by using CAD LMTD (Log MeanTemperature Difference) correction charts. This paper includes brief study review of the literature on Mean Temperature Difference to date and comparison of the graphs of Bowman and Ronald has been made. Further, The study has been extended to CAD LMTD correction charts for automated design. These charts have shown prominent to the user and provide good results with greater reading ability and accuracy

Title	:	Analysis Of An Active Vehicle Suspension System With Controllers Using Simulation
Country	:	India
Authors	:	Dr. Bejagam Naga Raju || Bonu Naveen Kumar || Payaavula Rajendra Mouli

Abstract: Traditionally automotive suspension designs have been a compromise between three conflicting criteria of road holding, load carrying and passenger comfort. The suspension system must support the vehicle, provide directional control during handling maneuvers and provide effective isolation of passenger payload from road disturbances. Good ride comfort requires a soft suspension whereas insensitivity to applied load requires stiff suspension. Good handling requires a suspension setting somewhere between the two. The objective of the project is to develop an active control law for the suspension system , for this only a quarter model of the vehicle suspension system with two degree of freedom is conceived and then effect of various types of input (Step, impulse) on the passive.............

Title	:	Thermo Acoustic Refrigeration
Country	:	India
Authors	:	T. Somasekhar || P.Naveen Kishore

Abstract: Thermoacoustic refrigeration is an emerging refrigeration technology which does not require any moving parts or harmful refrigerants in its operation. This technology uses acoustic waves to pump heat across a temperature gradient. The vast majority of thermoacoustic refrigerators to date have used electromagnetic loudspeakers to generate the acoustic input. In this thesis, the design, construction, operation, and modeling of a thermoacoustic refrigerator are detailed. The developed theoretical and experimental tools can serve as invaluable means for the design and testing of other piezoelectrically-driven thermoacoustic refrigerator configurations.
