The influence of pressure on minimum fluidization velocity has been measured in a pressurized fluid&d bed. Three different bed materials, corresponding to Geldart' s group B or group D particles, were investigated at pressures between 0.1 and 1.6 MPa. The onset of Auidization was determined both vis
## Abstract The final quality of espresso coffee (EC) depends upon certain technical conditions, such as the extraction temperature used in preparing it. The aim of this work was to investigate the effects of water temperature (88, 92, 96 and 98βΒ°C) on the final quality of three types of EC (Arabic
Local shear diagrams and particle number densities were measured in the gap of two coaxial cylinders in gas fluidized beds of different dimensions by couette-and electric capacity techniques respectively. The flow equations were evaluated from the shear diagrams, fitted to sinh-functions and explain
