Bubbles were observed through a transparent front wall of the bed. The experiments were conducted with sand particles of an average size of 281 μm at an excess gas velocity above minimum fluidization of 12 cm/s. The bed employed a mild steel perforated plate with 88 holes arranged in square pitch. A static bed 70 cm in height was used in all cases. No change in bubble size and bubble rise velocity was detected when the bed was inclined at ± 0.8 degrees to the vertical. It was previously a concern that small variances from the vertical in a laboratory scale semicylindrical fluidized bed would indicate small changes in wall effects and prejudice experimental results obtained by direct observation through the transparent front wall of the bed.}, pages = {165--170}, title = {A study of small changes in bed inclination on wall effect in a semi-cylindrical fluidized bed}, volume = {28}, year = {1986} }
