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...
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...
The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...
