Effects of droplet parameters are reported using model simulations on the evaporation characteristics droplets containing insoluble nanoparticles and related to formation shells particles. The initial diameter (do), particle mass fraction (Yvo), Peclet number (Pe) based fluid rate constant (K) diffusivity in (Dpl). Time-dependent phenomena instantaneous size (d), d2 vs time (for example, follow...

The potential for nanofuels as one of the clean sources of energy on account of its enhanced combustion performance coupled with low emissions has been established. Considering the importance of the fuel evaporation phase in the entire combustion process, this work presents an attempt at applying the steady state analysis equations to nanofuel experimental data obtained from the li...

In a wide range of applications, the estimate droplet evaporation time is based on classical d2-law, which, assuming fast mixing and fixed environmental properties, states that surface decreases linearly with at determined rate. However, in many cases predicted rate overestimated. this Letter, we propose revision d2-law capable to accurately determine dilute conditions by proper asymptotic prop...

In this paper we study the distribution of pairs (d1, d2) of positive integers such that the product d1d2 divides a given integer n from a probabilistic point of view. The number of these pairs, denoted by τ3(n), is equal to the number of ways to write n as a product of three positive integers. To these pairs we associate a random vector taking the values ( (log d1)/(log n), (log d2)/(log n) ) ...

Let d = 1 ≤ d1 ≤ d2 ≤ · · · ≤ dn be a non-decreasing sequence of n positive integers, whose sum is even. Let Gn,d denote the set of graphs with vertex set [n] = {1, 2, . . . , n} in which the degree of vertex i is di. Let Gn,d be chosen uniformly at random from Gn,d. Let d = (d1 + d2 + · · ·+ dn)/n be the average degree. We give a condition on d under which we can show that whp the chromatic nu...

Studying how individuals compare two given quantitative stimuli, say d1 and d2, is a fundamental problem. One very common way to address it is through ratio estimation, that is to ask individuals not to give values to d1 and d2, but rather to give their estimates of the ratio p = d1/d2. Several psychophysical theories (the best known being Stevens’ power-law) claim that this ratio cannot be kno...

Studying how individuals compare two given quantitative stimuli, say d1 and d2, is a fundamental problem. One very common way to address it is through ratio magnitude estimation, that is to ask individuals not to give values to d1 and d2 but rather to give their estimates of the ratio p = d1/d2. Several psychophysical theories (the most known being Stevens’ power-law) claim that this ratio cann...

The differences in the observed properties of solid H2 and D2 are reviewed, and in particular those encountered in NMR experiments. The failure to detect a sharp NMR (I=1) impurity ‘‘isolated pair’’ spectrum in p-D2 is discussed in terms of a larger crystalline field than in H2, where an intense and sharp pair spectrum has been observed. Furthermore, we discuss the dramatic (I=1) solid echo sig...

A new divertor concept REVOLVER-D2 that uses metal pebbles as a target has been proposed for the LHD-type helical fusion reactor FFHR-c1. Demonstration of sufficient plasma shielding rate is one important issues to show feasibility REVOLVER-D2. For this purpose, an experiment on irradiation pebble flow conducted in sheet device TPDsheet-U Tokai University. Reduction ion flux and electron densit...
