The paper presents a theoretical analysis of heat transfer in a heated tube bank, based on the Nusselt number computation as one of the basic dimensionless criteria. To compute the Nusselt number based on the heat transfer coefficient, the reference temperature must be determined. Despite the value significance, the quantity has several different formulations, which leads to discrepancies in results. This paper investigates the heat transfer of the inline and staggered tube banks, made up of 20 rows, at a constant tube diameter and longitudinal and transverse pitch. Both laminar and turbulent flows up to Re = 10,000 are considered, and the effect of gravity is included as well. Several locations for the reference temperature are taken into consideration on the basis of the heretofore published research, and the results in terms of the overall Nusselt number are compared with those obtained by the experimental correlations. This paper provides the most suitable variant for a unique reference temperature, in terms of a constant value for all tube angles, and the Reynolds number ranges of 100–1000 and 1000–10,000 which are in good agreement with the most frequently used correlating equations.

The wide usage of heat exchangers in various industrial applications has attracted the attention of many researchers. An experimental and theoretical study was conducted to investigate the fluid flow across a longitudinal fin flat tube heat exchanger with laminar forced convection. The studied parameters were the dimensionless longitudinal pitch length (, dimensionless transfer pitch (3 ≤ ≤ 5), dimensionless downstream fin length (), dimensionless upstream fin length (), dimensionless downstream fin angle (), and Reynolds number (223 ≤ Re ≤ 1114). The studied air thermophysical properties were assumed constant. The study was conducted under constant surface temperature. The dimensionless pressure drop was reduced by 60.8% (at Re = 223 as increased from 3 to 5), 4.69% (at Re = 1114 as decreased from 5 to 4), 225% (at Re = 223 as decreased from 1 to 0.4), 6.9% (at Re = 1114 as decreased from 1 to 0.4), and 349.9% (at Re = 668 as decreased from 0.79 to 0.26). The difference between the experimental and numerical data was insignificant. Two correlations were developed based on the present experimental and numerical results.
