Heat transfer in packed bed

Input(s)

a: Number of Particles in Bed (dimensionless)

Sdz\mathrm{S}_{\mathrm{dz}}: Representative Volume for Each Particle (m3)\left(\mathrm{m}^{3}\right)

ToT_{o}: Final Temperature (K)(\mathrm{K})

TbT_{b}: Initial Temperature (K)(\mathrm{K})

hloc h_{\text {loc }}: Heat Transfer Coefficient (W/mK)(\mathrm{W} / \mathrm{m} \mathrm{K})

Output(s)

dQ: Heat Loss (J/s)(\mathrm{J} / \mathrm{s})

Formula(s)

dQ=hloca(Sdz)( ToTb)\mathrm{dQ}=\mathrm{h}_{\mathrm{loc}} * \mathrm{a} *(\mathrm{Sdz}) *\left(\mathrm{~T}_{\mathrm{o}}-\mathrm{T}_{\mathrm{b}}\right)
