“…Figure shows that the enhancement ratio passes through a maximum at an impeller rotation speed of 600 rpm, especially at low resin concentrations. This phenomenon is consistent with the results obtained in studies on the effects of fluidized beds on the rate of heat and mass transfer at the walls of a container. The initial increase in the enhancement ratio with increasing impeller rotation speed can be ascribed to the increase of the kinetic energy of the particles. After reaching a maximum value, the rate of transfer decreased with further increases in the impeller speed because of the decrease in the number of particles per unit volume hitting the transfer surface, as the bed expansion increased with increasing impeller rotation speed.…”

“…This measuring technique has been especially used for prior studies of the processes occurring in the boundary layer at the wall of the apparatus [2]. Also in chemical engineering this method has been used, for example: in the studies of pulsate and oscillate flows between parallel plate (plate heat exchanger) [3][4][5][6], in evaluation of the thickness of boundary layer in natural convection mass transfer [7][8][9], in the measurement of liquid film thickness in Newtonian [10] and non-Newtonian fluids [11], in pipes flow [12][13][14][15], in packed column [16,17], in fluidisation processes [18,19] and membrane reactor [20].…”

“…The solution was subsequently analyzed for the concentration of solution-phase Fe͑VI͒. [18][19][20][21][22][23][24][25][26][27] Alternately, in this study we develop an in situ electrochemical methodology for the direct synthesis of barium ferrate in the solid state. 16 This electrochemical synthesis of salts eliminates the need for chemical oxidants and decreases the synthesis complexity.…”
