“…Therefore, the augmented-NTU, referred to as NTU Ã , associated with U = 0.3, R = 0.5, and NTU = 40 is 90.5. This approach is analogous to the idea of using a pseudo-Stanton number or apparent heat transfer coefficient to account for particle internal conductivity or axial dispersion, as described by Jeffreson [12]. Notice that the range of NTU shown in Fig.…”
