Experimental and Numerical Investigation of Four- Phase Flow (Water–Gasoline-Air-Solid) in a Fluidized Bed Column

Abstract

In this paper four phase fluidized bed is experimentally built and numerically modeled to study the bed characteristics such as ratio (the static bed height of solid particle / the bed diameter (H/D)), air, gasoline , and water superficial velocity. The test pipe for the experimental rig is Perspex pipe with 1 m long and 0.0254 m diameter. The 2D numerical model has been established with Ansys fluent 15.0. Pressure drop equation is found to relate the pressure drop with the bed parameters with deviation of 22%. The Four-phases was represented by air, water, gasoline and solid particle. The results show that the pressure of the bed increases as the ratio H/D increases and air, gasoline , and water superficial velocity increases. As well as the expansion of the bed increases as air, gasoline, and water superficial velocity increases.
