Because of the time and expense involved in conducting laboratoiy distillation tests of all three basic types, it has become increasingly common to use empirical correlations to estimate the other two distillation curves when either the ASTM, TBP, or EFN- curve is available. Preferred correlations given in the API Technical Data Book—Petroleum Refining (op. dt.) are based on the work of Edmister and Pollock [Chem. Eng. Prog., 44, 905 (1948)], Edmister and Okamoto [Pet. Refiner, 38(8), 117 (1959) 38(9), 271 (1959)], Maxwell Data Book on...

Up to this point, the discussion has been limited to cases where the adhesion-induced stresses result in elastic deformation. However, as previously discussed, this need not be the case. Indeed, these stresses can be, in many instances, comparable to the Young s moduli of the contacting materials, often resulting in plastic deformations. This area has been most notably explored by Maugis and Pollock [63]. 

According to the theory proposed by Maugis and Pollock, hereafter referred to as the MP model, if the adhesion induced stresses cause at least one of the contacting materials to yield and undergo a totally plastic response, the contact region formed will increase in size until the force causing the yielding is balanced... 

As also discussed by Maugis and Pollock, the hardness of the material is related to its yield strength Y by H = 2>Y. The factor of 3 is a consequence of the deformation constraints of the indentor geometry used in hardness measurements. In the absence of an applied load, the MP theory predicts that... 

An example of a Maugis-Pollock system is polystyrene particles having radii between about 1 and 6 p.m on a polished silicon substrate, as studied by Rimai et al. [64]. As shown in Fig. 4, the contact radius was found to vary as the square root of the particle radius. Similar results were reported for crosslinked polystyrene spheres on Si02/silicon substrates [65] and micrometer-size glass particles on silicon substrates [66]. 

The Webre design as tested by Pollock and Work [14] showed (Figure 4-50C) that internal action in the separator was responsible for some of the entrainment, particularly liquid creep up the vessel walls.
