Thus, the residence time is one of the fundamental parameters of the mill. Consequently, many studies have focused on the determination of the residence time distribution for various types of grinding mills operating in a continuous mode (Kelsall et al., 1969, Gardner et al., 1980, Rogers et al., 1982, Fuerstenau et al., 1986, Weller et al ...
Ch 24 Residence Time Pennsylvania State University. 2005321By definition, the residence time is the amount of material in the reservoir, divided by either the inflow or the outflow they are equal when the reservoir is at equilibrium If there are multiple inflows or outflows, then we use the sum of the outflows or inflows to determine the residence time For our bathtub system here, the residence
The residence time distribution of the gas phase in circulating fluidized beds (CFB) 5 The increasing interest in using a CFB for fast reactions underlines the importance of the gas hydrodynamics, subject of the present research. The study of the hydrodynamics of the particles has been published previously (Van de Velden et al., 2007b,c). 2.
