Description

  • Content Description: Task I - Extensional Viscometer - A contracting flow extensional viscometer was designed and constructed at Adelphi University. Calibration was conducted using a variety of fluids and suspensions. Task 2 - Testing using the extensional viscometer was performed using simulated fluids. Testing was performed using coal water slurries with dispersant and/ or stabilizer to determine the concentration and shear dependence and the effect of additives. Viscoelastic effects were evaluated using simulated fluids. Testing with coal at three coal concentrations to determine dependence will begin shortly. Task 3 - Extension of the Phenomenological Model - The phenomenological model is being extended to include extensional and viscoelastic properties. Task 4 - Development of Active Model for Atomization - A bench scale atomization study is being conducted using simulated fluids and coal water slurries to determine the parameters on which the model is dependent. Based on these results, a model is being developed for the Sauter mean diameter. A statistical analysis of atomization data will relate the PSD to the dimensionless parameters.
