    • Structural Characteristics Of Randomly Packed Beds Of Spheres 

      Rao, Ammavajjala V S (Indian Institute of Science, 2005-07-20)
      Packed beds find extensive application in a wide variety of industries to cany out a large number of diverse processes. The main objective of the present work is to develop models to predict the arrangement of particles ...

    • Prediction Of Separation Factor In Foam Separation Of Proteins 

      Bhattacharjee, Samita (Indian Institute of Science, 2005-07-20)
      Polyhedral foams offer large gas-liquid interfacial area associated with a small amount of liquid. Therefore, if a solute adsorbs preferentially at the interface, the concentration of the solute in the foam will be greater ...

    • A Model For Heat Transfer In A Honey Bee Swarm 

      Bask, Tanmay (Indian Institute of Science, 2005-07-20)
      During spring, it has been observed that several thousand bees leave their hive, and settle on some object such as a tree branch. Some of the scout bees search for a suitable place where a new hive can be set up, while the ...

    • Aqueous Phase Oxidation Of Sulfur Dioxide In Stirred Slurry Reactors 

      Gopala Krishna, K V (Indian Institute of Science, 2005-07-18)
      Air pollution by sulfur dioxide is of great concern due to its harmful effects on environment, human beings, fauna and flora. Fossil-fuel-fired power plants are one of the major sources of SO2 emissions. Typically the ...

    • An Autonomous Guidance Scheme For Orbital Rendezvous 

      Shankar, G S (Indian Institute of Science, 2005-07-15)
      The word 'rendezvous' implies a pre-arranged meeting between two entities for a specific purpose. This term is used in the study of spacecraft operations, to describe a set of maneuvers performed by two spacecraft in order ...
