heat flow due to a build-up of a layer of dirt or other fouling substance on the tube surfaces of the heat exchanger, but they are often overstated by the end user in an attempt to minimise the frequency of cleaning. In reality, if the wrong fouling factor is used, cleaning may ...

fouling factor [′fau̇l·iŋ ‚fak·tər] (chemical engineering) In heat transfer, the lowering of clear-film transfer rates resulting from corrosion, dirt, or roughness of the surface of tube walls of heat exchangers. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyri...
In fact, it is then possible to introduce an arbitrary fouling factor. Thus, in the first part of the paper the model of the heat exchanger is presented. It is developed using Simulink. The validation is carried out on an electrical heater, for which it is possible to find an analytical...
Information regarding deposit type would be useful in selecting an appropriate treatment procedure. Some cautions regarding the indiscriminate use of fouling factor or fouling resistance are also discussed.doi:10.1080/01457638408962772TURAKHIA, MCHARACKLIS, W. G...
Another important factor that causes stress corrosion is temperature. The higher the temperature is, the lower the density of chloride ions is, and the more easily stress corrosion will be caused. Biological Corrosion Biological corrosion frequently happens when the metal surface is in contact with ...
tube forming an extra layer of material, which often has a thermal resistance. It should not be confused with corrosion occurring under the fouling layer as mentioned previously. The careful use of corrosion-resistant materials such as stainless steel is a key factor in preventing corrosion fouling...
