Constantin et al. [13] deposited by direct current magnetron sputtering TiNx thin films onto high-speed steel, silicon and stainless steel substrates, from a pure Ti target, varying the flow rate of the reactive gas, a crystalline structure with fcc phase and strong (111) orientation of the peaks, obtained using the lowest nitrogen gas flow of 4.5 sccm and the most performing TiNx film was that one with small sized of the grains (around 8 nm), a higher value of hardness (18.4 GPa) and a good thickness of 1.5 μm were obtained also.
Enriquez-Flores et al. studied the microstructural and mechanical properties of titanium nitride (TiN) films.
DomínguezCrespo et al. deposited by R.f. magnetron sputtering on AISI 316L SS different Ti/TiN coatings in order to study the effect of sputtering conditions on tribological and corrosion properties.
Ajenifuja et al, sputtered with different thicknesses of TiNx thin film with varying time from 5 to 20 min, using DC reactive magnetron sputtering technique.

For high values of Pe, the mass transfer process is dominated by advection and the CDS scheme is not bounded [19], and to resolve this unbounded property [20] the CUBISTA scheme proposed by Alves et al. [21] was used.
So, for an exterior temperature of 293.15 K, an air velocity of 0.32 m/s and an initial air relative humidity of 60%, in the box, the is given by: (47) and inserting these values into Eq. (44), an evapouration potential for the HUMIVENT system, eL, of 0.0037 mm/min is obtained.
So, for the same conditions described above (, and ) and inserting these values into Eq. (44), an evapouration potential, eL, of 0.0033 mm/min is obtained.

Nejat et al. [1] performed numerical investigations of power-law fluid flows over a pair of identical circular cylinders which are confined in straight channel.
Salcedo et al. [2] presented in two dimensional simulations the mixed convection heat transfer from a pair of equal-sized cylinders of circular cross-section.
Mishra et al. [6] numerically studied the forced convection heat transfer of non-Newtonian power-law fluids through a ventilated cavity where there are two circler cylinders placed in tandem and side-by-side arrangements.
The work has tested the influence of cylinders arrangement, Reynolds number and power-law index on flow patterns and heat transfer. karimi et al. [7] numerical investigation has been carried out to study the steady-state mixed convection heat transfer from two circular cylinders placed at the center of ventilated cavity with tandem arrangement.
Talkhoncheh et al. [8] numerically investigated the forced convection heat transfer of two horizontal circular cylinders placed in tandem arrangement inside a square cavity, the enclosure is ventilated.

Khelladi et al. [2], Ballesteros-Tajadura et al. [6], Lin. [7], Youni et al. [8] and Liu et al. [9] studied fan noise radiation through the following approach: unsteady flow fields firstly are obtained by CFD, then sound sources are extracted, and finally sound radiation to free field is calculated through FW&H equation (the general form of Lighthill’s acoustic analogy theory, we discuss it in Section 4) ignoring the presence of casings.
Koopmann et al. [10] employed BEM with experimental vibration data of the casing to compute the casing noise radiation of a centrifugal fan; in this study, we used FEA technique to obtain the vibration data.
