Heat transfer in packed bed
Input(s)
a: Number of Particles in Bed (dimensionless)
\(\mathrm{S}_{\mathrm{dz}}\): Representative Volume for Each Particle \(\left(\mathrm{m}^{3}\right)\)
\(T_{o}\): Final Temperature \((\mathrm{K})\)
\(T_{b}\): Initial Temperature \((\mathrm{K})\)
\(h_{\text {loc }}\): Heat Transfer Coefficient \((\mathrm{W} / \mathrm{m} \mathrm{K})\)
Output(s)
dQ: Heat Loss \((\mathrm{J} / \mathrm{s})\)
Formula(s)
\[
\mathrm{dQ}=\mathrm{h}_{\mathrm{loc}} * \mathrm{a} *(\mathrm{Sdz}) *\left(\mathrm{~T}_{\mathrm{o}}-\mathrm{T}_{\mathrm{b}}\right)
\]
