Bubble formation on a single orifice in a gas solid fluidized bed using digital image analysis

A. Dehghan Lotfabad; S. Movahedirad; M.T. Sadeghi

Volume 13, Issue 1 , January 2016, , Pages 60-72

  Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, ...  Read More

Study of Carbon Black Production with Optimized Feed to Predict Product Particle Size
Volume 4, Issue 1 , January 2007, , Pages 36-42

  Carbon black or soot is a carbon rich material which is widely used as a modifier and filler. Usually carbon black is produced via thermal decomposition of heavy hydrocarbons. This process is too complex to be modelled fundamentally. In this study, the effect of reaction feed composition on the soot ...  Read More
