Some early spray models were based on the combination of a discrete droplet model with a multidimensional gas flow model for the prediction of turbulent combustion of liquid fuels in steady flow combustors and in direct injection engines. In an improved spray model,[438] the full Reynolds-averaged Navier-Stokes equations were... 

To summarize, to properly model liquid water transport and ensuing flooding effect on cell performance, one must consider four submodels (1) a model of catalytic surface coverage by liquid water inside the catalyst layer, (2) a model of liquid water transport through hydrophobic microporous layer and GDL, (3) an interfacial droplet model at the GDL surface, and last (4) a two-phase flow model in the gas channel. Both experimental and theoretical works, in academia and industry alike, are ongoing to build models for the four key steps of water generation, transport, and removal from a PEFC.

FMO-MD simulations at HF/6-31G for reaction 15 were carried out by using a water droplet model, in which CH3-N2+ was located at the center of gravity of a sphere consisting of 156 water molecules.102 The initial structure of CH3-N2+ was taken from the gas-phase optimized structure at HF/6-31G, which was equilibrated in the water droplet with the substrate structure fixed...

To deduce this proportionality factor for T1 we assumed zero deformation for 207T1 (which is one proton from double magic 208Pb) and 200T1. We then use the droplet model [MYE83] to extract deformations from the field shifts. Droplet model values of 6 with 3 = 0 are fit to the two points of zero deformation and predictions for different deformations are shown as solid lines in Figure 3.

The IS s of nuclei far from stability turned out to be the most informative data obtained by optical spectroscopy. This is because the nuclear charge radius depends on collective as well as on single-particle effects. The integral IS s (6 with A being a reference isotope) exhibit the gross behaviour of nuclear matter as a function of varying neutron number. These can be compared with predictions of macroscopic models like the Droplet Model [MEY83], which describes the overall trend quite well. 

The emphasis of the present chapter is on the droplet model, and the methodology used in the treatment is a thermodynamic one. While the information obtained is incomplete, it will be shown that thermodynamics can provide understanding regarding...

The bundlet model for clusters of SWNTs was presented in [1], The aim of this report is to perform comparative study of properties of fullerenes, SWNTs and single-wall carbon nanocones (SWNCs) [2], A wide class of phenomena accompanying behaviour of SWNT-SWNC solutions is analyzed from unique point of view, taking into account tendency to cluster formation [3]. Based on droplet model of Ceo-SWNCs a bundlet model of SWNTs is proposed in [4]. SWNCs are model of complex systems (BN SWNCs) [5]. 

Fig. 1. General oil-droplet model of lipoproteins is presented for chylomicron, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) structures. Apolipoproteins in the outer phospholipid membrane, designated by letters, are defined in Table II. The major differences between the lipoproteins are the size of the neutral lipid (triglyceride and esterified cholesterol) core, liquid composition in the core, and apolipoprotein composition. (E) Triglycerides, ( Q ) phospholipids, and ( -) esterified cholesterol are shown. Although not shown, unesterified cholesterol is found predominantly in the phospholipid monolayer.

The simplest representation of the structure of microemulsions is the droplet model in which microemulsion droplets are surrounded by an interfacial film consisting of both surfactant and cosurfactant molecules, as illustrated in Fig. 7.18. The orientation of the amphiphiles at the interface will, of course, differ in o/w and w/o microemulsions. As...
