Heat transfer between a surface and a fluidized bed: consideration of pressure and temperature effects

Heat transfer characteristics in a pressurized fluidized bed of fine particles with immersed horizontal tube bundle

“…A comparison between the calculated values of Nu max from the correlations relevant to the pressure effect on heat transfer in the literature [22][23][24][25][27][28][29][30][31][32] and the experimental values from the present and previous studies [9,10,18,24,26] is shown in Table 2. As can be seen, the present correlation considering bed fluidization quality around the tube predicts the Nu max values most accurately compared with the values from the reported correlations.…”

Energy-efficient fluidized bed drying of low-rank coal

“…The heat transfer coefficient relative to the horizontal heat exchange tubes immersed in the fluidized bed, a t , was calculated using [13,14] Nu t ¼ 0:74 Ar 0:1 ρ s ρ g ! 0:14 C ps C pg 0:24 υ s 2 = 3 þ 0:46 Re Pr…”

Innovative Energy‐Efficient Biomass Drying Based on Self‐Heat Recuperation Technology

“…An approximation of heat exchange based on previously conducted research [30,[33][34][35][36] was performed to evaluate the kinetics of the heat transfer rate occurring inside the FBD and to approximate the required length, L, of the heat transfer tube inside the FBD. This was also important for predicting the feasibility of heat exchange in the proposed drying system.…”
