Correction factor for the logarithmic mean temperature difference (LMTD) to make it applicable to heat exchangers in which the flow is not entirely counter-current or co-current. Mass velocity (mass flow rate of fluid per unit cross-sectional area for flow).

Cataloged performance data includes a "fouling factor" that accounts for this effect to more closely predict actual chiller performance. ... Assessing a smaller fouling factor lets specifying engineers, owners, and manufacturers alike take credit for seemingly better heat transfer.

Fouling - Wikipedia, the free encyclopedia
Fouling refers to the accumulation of unwanted material on solid surfaces, most often in an aquatic environment. The fouling material can consist of either living organisms (biofouling) or a non-livi...

If you specify a fouling factor, they will probably either ignore it or take exception to it. A vast majority of plate and frame exchangers are single pass on both sides. To add surface, there are two choices: (1) add more plates or (2)use bigger (longer) plates.

I'd like to know the formula that permit to correlate the value of heat transfer coefficient in case of an heat exchanger with and without fouling, with the value of the fouling factor.

Q: How do you calculate the fouling factor in a plate heat exchanger? ... A: Fouling factors are generally not applied in a plate heat exchanger design. The preferred method for plate heat exchangers is to design clean and add approximately 10% excess surface. Plate exchangers, which are properly designed with sufficient...

In sizing a heat exchanger the fouling factor is always indicated and pressure drop is then calculated. Very often the fouling layer thickness is omitted in the calculation, resulting in clean pressure drop rather than required fouled pressure drop. ... In finding out fouling layer thickness, one will need the fouling...
