DEFINITION OF CRITICAL AREA OF MAGNETICALLY STABLE FLUIDIZATION WITH WAVE THEORY
In this paper, the critical area of magnetically stable fluidization is defined with wave theory.The definition is made in the following steps.First,the void fluctuation equation is established from two-phase model of magnetically fluidized beds(MFBs).Then,the void fluctuation in MFBs is analyzed with wave theory and the criterion of critical area of magnetically stable fluidization is derived.The critical area of magnetically stable fluidization defined in this paper matches well with the experimental results.
