The present article aims to investigate the effect of electrostatic field and temperature on the distribution of chloride and sodium ions during the saltwater flow in a horizontal channel. The change in the intensity of the uniform electric field has been controlled by applying DC high-voltage between the horizontal walls of the channel, where this field creates an electric force that deviate the positive and negative ions towards the walls in opposite directions, which results a large space in the middle of fluid almost free of dissolved salt. The proposed study is formulated with a system of coupled partial differential equations in the Navier-Stokes equation and energy. In addition, the Buongiorno equation was used to study the distribution of ion concentration in seawater. Important results were obtained in this numerical study, including that the increase in the intensity of the electric field and temperature significantly reduced the concentration of cations and anions in a wide area of seawater, thus obtaining a large amount of diluted water. The distribution of sodium and chloride ion concentration, the flow, the horizontal velocity, and the isotherms were modeled under the electrostatic field intensity variation factor and Reynolds number for an accurate, detailed, and clear interpretation.

For carbon steel (CS) in a corrosive hydraulic acid solution, various quantities of the molecule 3-phenyl-isoxazoline-carvone (PIC) were employed (1M; HCL). The inhibitory effects of the 3-phenyl-isoxazoline-carvone (PIC) were evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), weight loss, surface morphology analysis (SEM), quantum chemical calculations (DFT), and Monte Carlo simulations (MC). According to the findings, the compound, 3-phenyl-isoxazoline-carvone (PIC) is a mixed-type inhibitor that significantly decreased the rate of carbon steel (CS) corrosion by creating a protective coating on the carbon steel surface (CS). According to EIS, PDP, and mass loss studies, the molecule 3-phenyl-isoxazoline-carvone (PIC) is a stronger corrosion inhibitor, with corrosion effectiveness of about 95% at 298 K temperature. Adsorption of the 3-phenyl-isoxazoline-carvone (PIC) molecule on the surface of carbon steel includes both physisorption and chemisorption, according to the Langmuir isotherm model. Aside from experimental methods, theoretical methods such as DFT simulations, molecular dynamics simulations, and the radial distribution method were used to provide detailed knowledge about the mechanism of corrosion inhibition and to reveal factors controlling the efficiency of the investigated inhibitor.
