LMTD correction factorNumerical methodologyThis paper outlines the application of a numerical procedure to compute the LMTD correction factor for one tube pass and one shell pass, namely 1-1, shell-and-tube heat exchangers. Although the procedure was applied for this specific arrangement, it can ...
Solution:The Ft factor (LMTD Correction Factor) is related to the shell & tube configuration (...
The presented numerical methodology allows the direct computation of the LMTD correction factor for a determined arrangement, giving a new perspective on the project and sizing of shell-and-tube heat exchangers, since typically the analytical solution is applied for all arrangements.Luiz Gustavo ...
This new approach results in a single general algebraic equation for determining the LMTD correction factor of multi-pass shell and tube heat exchangers with any number of shell passes and even number of tube passes per shell. The correction factor thus obtained is a function of number of ...

The model was based on the LMTD and e-NTU methods, where a LMTD correction factor was taken into account to increase accuracy. An experimental apparatus was set-up to validate the model. Results showed that errors of thermal duty, outlet hot fluid temperature, outlet cold fluid temperature, ...
= 1.0 for pipe-in-pipe and countercurrent = 1.0 for boiling or condensing of pure components A common presentation of MTD information is F-factor graphs, where F is defined as the actual mean temperature difference (MTD) divided by the “log mean temperature difference” (LMTD). The LMTD is...
It will be shown through integration of the governing equations that the LMTD approach indeed may be used for practical cases, even though deviations occur at small logarithmic mean temperature differences. The article presents suggestions on the correction factor ( F) needed under some simplified ...
aa1701955@qu.edu.qa Abstract: This paper expands a recently proposed peak current-mode (PCM) control method for a power factor correction (PFC) boost converter to include the totem-pole converter and solves the controller's compatibility problem with the totem-pole converter by proposing three in...
