Two pass shell heat exchanger with longitudinal baffle.

[Twink21]

Hello engineers,

I am trying to find the coefficient called the "Correction Factor" for Log Mean Temperature Difference (LMTD) for this type of a heat exchanger. I cannot find the coefficient or any diagrams for this particular one in the literature. Does anyone know how to determine it? It is almost perfect countercurrent, I suppose it should be near 0,9.

Based on there being a perfect seal of the long baffle, and two tube passes, I would use a LMTD correction factor of 1.0.
