[mu] > 0 denotes viscosity coefficient, [kappa] > 0 is the Weber number and [lambda] > 0 is the Debye length. The unknown functions are the density n, the velocity u and the electrostatic potential [PHI], respectively.
where [[kappa].sup.-1] is called the Debye length ([[lambda].sub.D]) that gives a measure of the EDL and [N.sub.A] is the Avogadro number.
Increment of conductance of channel and [I.sub.ON] alongside the increase of electrolyte concentration is associated with Debye length, [[lambda].sub.D].
tan[([phi]).sub.max] = [square root of [delta]]/2 at [[tau].sub.2] = [[tau].sub.1] [square root of [delta]] (2) The Debye length [[lamabda].sub.D] is calculated as the ratio of a sample thickness, d with the dimension-less, [delta]:
For solar studies, the radar wavelength must be longer than the Debye length, a characteristic length scale in a plasma.
Table 1 shows the calculated values of Debye length ([[lambda].sub.D]), plasma frequency ([f.sub.p]) and Debye number ([N.sub.d]) for DC discharge in argon gas at the three regions with different applied voltage.
Nanofluidic devices, such as organic or inorganic pores and channels, have primary dimensions comparable to the Debye length, and so they have been wildly used for the successful separation of DNA or biomolecular sensing down to the single-molecule level [6-10].
Ionic strength (I) of the buffer solution determines an important parameter, the Debye length the length in which mobile charge carriers screen out the external electric field, causing small charge movement (Fig.
The Debye length of the colloidal systems ranging from 4.48 to 8.20 nm is plotted in Figure 2(d).
In a plasma, it is well known that a given charge is shielded by the surrounding ones, so that at a certain distance called the Debye length, the charge has no effect.
where k = [([OMEGA][[lambda].sup.2]/[mu]).sup.1/2] is a normalized parameter expressed as a function of the Debye length ([lambda]), the electric field excitation frequency ([OMEGA]), and the kinematic viscosity ([mu]).
