An experimental study of radiative and total heat transfer between a high temperature fluidized bed and an array of immersed tubes

Creator:: Lei, David Hsien-Yu
Abstract:: Experimental data are reported for the time-averaged local radiative and total heat transfer coefficients for both an array of horizontal tubes as well as a single horizontal tube immersed in a large-particle fluidized bed at elevated temperatures. Spatial-averaged heat transfer coefficients computed from the local values, using a simple trapezoidal...

Experimental studies of heat transfer with an array of horizontal tubes immersed in a high-temerature fluidized bed

Creator:: Goshayeshi, Ali
Abstract:: An experimental study is described in which time-average local heat transfer coefficients were obtained for arrays of horizontal tubes immersed in a hot fluidized bed. Spatial-averaged heat transfer coefficients, computed from local values, are also reported. Refractory particles with surface mean diameters of 2.14 mm and 3.23 mm were fluidized...

Moving bed heat transfer and fluidized elutriation

Creator:: Colakyan, Manuk
Abstract:: Two problems relating to the processing of solid streams are treated in two sections. The first section is the study of heat transfer between an immersed cylinder and a moving bed of solids: An instrumented heated cylinder was placed in the flow stream of a moving bed of solids with...

A theoretical study of the radiative contribution to heat transfer between a high-temperature, large-particle gas-fluidized bed and an immersed tube

Creator:: Mahbod, Bahram
Abstract:: An analytical model of the radiative contribution to the total heat transfer between a large-particle (greater than 1 mm) gas-fluidized bed and an immersed horizontal tube is discussed. The model is applied to the case of a bubbling bed and the emulsion phase contribution is obtained from a detailed analysis...
