hello all, i am new to cfx. working on ansys cfx 10.0 i am workin on a gas liquid and solid fludized bed. with water as continous fluid and air as dispersed fluid. how will u specify the volume fraction of solid particles in the bed. i am trying with the schiller-nauman model for liquid-solid pair and grace model for water-air pair. in results i got both air and water volume fractions but zero solid fraction. how is this happening. please help me out. thanaq
