Ting model

To confirm this conclusion, we incorporate the effects of adhesion into the Ting model using an empirical approach suggested by Falsafi et al. (31) They replaced the load P in equation 8 with an effective load Pgff calculated from JKR theory, i.e.,... 

Important exceptions to McCabes gro th-rate model have been noted by Bramson, by Randolph, and by Abegg. These are discussed by Canning and Randolph, Am. Inst. Chem. Ting. J., 13, 5 (1967). 

A model of a reaction process is a set of data and equations that is believed to represent the performance of a specific vessel configuration (mixed, plug flow, laminar, dispersed, and so on). The equations include the stoichiometric relations, rate equations, heat and material balances, and auxihaiy relations such as those of mass transfer, pressure variation, contac ting efficiency, residence time distribution, and so on. The data describe physical and thermodynamic properties and, in the ultimate analysis, economic factors.

A second important aspect of physical accuracy has a decidedly sociological tinge to it How accurately does the property of interest need to be predicted in order to make a useful scientific judgment The answer to this important question varies significantly across scientific disciplines and even subdisciplines and depends strongly on what the information from a calculation will be used for. The answer also evolves over time studies that were the state of the art 5, 10, or 20 years ago often become superceded by new approaches. This evolution of ideas due to the appearance of new methods is probably more rapid in computational modeling of materials than in experimental arenas, although it is important in both areas. 

Current work with supercritical fluids can also illustrate the importance of cosolvents. Cosolvent effects in supercritical fluids can be considerable for systems where the cosolvent interacts strongly with the solute. A correlation suggests that both physical and chemical forces are important in the solvation process in polar cosolvent supercritical CO2 mixtures. The model coupled with the correlation represents a step toward predicting solubilities in cosolvent-modified supercritical fluids using nonthermody-namic data. This method of modeling cosolvent effects allows a more intuitive interpretation of the data than either a purely physical equation of state or ideal chemical theory can provide (Ting et al., 1993). 

PSI PARTICLE. Discovery of this subatomic particle in 1974 was announced independently by Ting (Brookhaven National Laboratory) who named it the J particle and by B.D. Richter (Stanford) who named it the psi particle. The discovery of this particle resolved a number of important problems in particle physics. Intensive research on the psi particle was carried out by Richter and the Stanford group during 1975 and 1976 and is reported firsthand by Richter (Science, 196, 1286-1297.1977). As pointed out by Richter, the four-quark theoretical model became much more compelling with the discovery of the psi particles, The long life of the psi is explained by the fact that the decay of the psi into ordinary hadrons requires the conversion of both c and c into other quarks and antiquarks.

Several modifications of the OPDA procedure have been reported for automated analysis. Kirk and Ting (16) described a continuous flow analysis in which DCIP was substituted for Norit in the oxidation step. TAA and DHA can be determined directly RAA is calculated as the difference between TAA and DHA. Good agreement between the manual and automated procedures was achieved, with a considerable decrease in analytical time for the automated assay. Kirk and coworkers (17 19) have used the continuous flow analysis for studies of the kinetics of ascorbic acid degradation in model systems. 

Help in choo.ting the appropriate thermodynamic model in solving problems, and in using process simulators. 1 have put more emphasis on helping students choose the appropriate thermodynamic model for their separations and design courses, and on the use of process simulators, such as Aspen, Hy,sys, SimSci, and Chemcad, Thi.s is especially evident in Sec. 9.11.
