Experimental study and CFD simulation of two-phase flow (water-solid)‎ in fluidized bed column

الملخص EN

The static pressure of two phase ( liquid - Solid ) fluidized bed was investigated experimentally in this work for different values of the ratio static bed height over the diameter of the bed column (H/D) (0.59, 0.98, 1.38) and liquid phase velocity (0.16, 0.49, 0.82 m/s).

As well as the expansion of the bed visualized experimentally has compared with the solid volume fraction found numerically.

The fluidized system consists of glass test pipe of 1m height and 0.0254 m diameter inserted with stainless steel particles of 1.5 mm diameter fluidized by water.

Pressure was measured by pressure sensor located at four tapes on the side of the fluidized bed pipe.

High speed camera was used to photograph the flow in the test pipe.

The experimental results compared with computational fluid dynamics model simulated by ANSYS FLUENT version 15.0.

The results were in a good agreement with the experimental data
