Effect of the number of orifices and operative variables on the heat and mass transfer in a hydrofluidization system with static spheres

Sensitivity analysis using a model based on computational fluid dynamics, discrete element method and discrete phase model to study a food hydrofluidization system

“…In general, the velocity contours were similar to those described by Belis et al (2015). High local velocities are observed close to the zones where jets are developed.…”

“…The effect of the variables was similar to that observed for C NaCl . To summarize the information, a characteristic freezing time necessary for the center to reach −4 °C (t C ) was defined (Belis et al, 2015). To compare the freezing times, a relative freezing time (t R ) was defined as the ratio of t C at a certain condition to the t C corresponding to the condition T10V118S1E61 (Fig.…”

“…The modeling approach of HF has evolved through different configurations (Belis et al, 2015;Peralta et al, 2007Peralta et al, , 2009Peralta et al, , 2010Peralta et al, , 2012Verboven et al, 2003). Although, the main heat and mass transfer parameters were thoroughly studied and related to the operative variables, the movement of the particles and its effect on the transport phenomena needed to be modeled.…”
