Speech Title: Rheodynamic Lubrication of an Externally Pressurized Thrust Bearing using Yield-Stress Fluids


Abstract: Externally pressurized fluid film bearings have been the topic of numerous investigations over the last three decades. During this period not only has the fundamental understanding of the subject has developed, but also a variety of industrial applications of such bearings has encouraged the development of several design procedures. Considering its potential advantages including low viscous running friction, high load carrying capacity and high positional accuracy, externally pressurized thrust bearings are widely used in many applications such as machine tools, turbine generators, radio telescopes, radar antennas, etc,. Recently, the researchers intend to use non-Newtonian fluids as lubricants. Further, the interest has been increasing to use non-Newtonian fluids, in particular characterized by a yield-value such as Bingham, Casson and Herschel-Bulkley fluids. The continuing trend in lubrication industry emphasize that, in order to analyze the performances of the bearing, it is necessary to take into account the combined effects of fluid inertia and viscous forces of the lubricant. Hence, the study of lubricant inertia is assuming greater importance. Using the Herschel-Bulkley fluids as lubricants, the problems of different types of bearings have been investigated by many researchers. In the present work, the combined effects of fluid inertia and viscous forces on the bearing performances of an externally pressurized circular thrust bearing using Herchel C Bulkley fluids with sinusoidal injection have been analyzed. Numerical solutions are obtained for the film pressure and the load carrying capacity for various values of Herschel C Bulkley number, Reynolds number, power C law index and time at different amplitudes of Sinusoidal feeding. The effects of fluid inertia forces and the non-Newtonian characteristics of the Herschel C Bulkley lubricant on the bearing performance for different sinusoidal conditions have been discussed.

Speech Title: Fundamental of Nanofluids and Dynamic Modeling


Abstract: The term nanofluid is envisioned to describe a solid-fluid mixture which consists of nanoparticles and a base fluid, and which is one of the new challenges for thermo science. Nanotechnology plays an important role in the development of the 21st century modern devices for practical use. One very important aspect of nanotechnology concerns the heating, cooling and cleanliness of nano-devices because it is crucial for proper functionality. In this talk the fundamental of nanofluids, their evolution and applications in nanoscience and nanotechnology are explored. An advanced mathematical model is proposed to investigate the convective heat transfer mechanism in nanofluids along with deposition of nanoparticles due to thermophoresis and Brownian diffusion with different flow and thermal conditions. The mathematical model of the proposed nanofluid problem is simulated numerically. The results are interpreted physically and their implications are identified.
