“…In these processes, heat is generally transferred by conduction and convection between a solid surface and particles that move relative to the surface. Over the last fifty years, there has been a continued interest in the role of system parameters and in the mechanisms of heat transfer between granular media and the boundary surfaces in fluidized beds [3][4][5][6][7], dense phase chutes, hoppers and packed beds [8][9][10][11][12][13][14][15], dryers and rotary reactors and kilns [16][17][18][19][20]. More recently, experimental work on fluidized bed calciners and rotary calciners/kilns have been reported by LePage et al [21], Spurling et al [22], and Sudah.…”

“…Other granular properties also have special effects, which stem from the friction, dissipation, and size effect of granules. These effects lead to phenomenons in granular flow, such as the jamming and dilatancy properties prevent flow channel collapse [31]; while dissipation property prevents long-range disturbance propagation [32].…”

High power target systems require reliable high-temperature heat transfer media. Dense granular flow materials have potential to work as heat transfer media, especially at high temperature. In this chapter, a brief review of dense granular and their heat transfer properties is introduced, including basic concepts of heat transfer, thermal behavior of these materials, and factors that affect this behavior. The implementation of these materials as targets is addressed, where two targets were designed, constructed, and tested based on the concept of dense granular flow. The results of the application of a hopper flow-type target in 2.5 MW accelerator-driven system (ADS) and a chute flow-type target in the material irradiation facility will be presented.

“…In these processes heat is generally transferred by conduction and convection between a solid surface and particles that move relative to the surface. Over the last 50 years, there has been a continued interest in the role of system parameters and in the mechanisms of heat transfer between granular media and the boundary surfaces in fluidized beds (Mickey and Fairbanks, 1955;Basakov, 1964;Zeigler and Agarwal, 1969;Khan, 2002), dense phase chutes, hoppers and packed beds (Schotte, 1960;Sullivan and Sabersky, 1975;Broughton and Kubie, 1976;Spelt et al, 1982;Patton et al, 1987;Thomas et al, 1998), dryers and rotary reactors and kilns (Lehmberg et al, 1977;Whitaker, 1977;Perry and Chilton, 1984;Lybaert, 1986;Malhotra, 1991;Boateng and Barr, 1998). In many of these studies, empirical correlations relating bed temperature to surface heat transfer coefficients for a range of operating variables have been proposed.…”
