“…Moreover, it has also been found , that the intensity of the magnetic field has to be high to be able to cause a reduction in surface tension, which confirms the reliability of our surface tension results. In summary, a magnetic field has the ability to alter electric charges in favor of alterations in wettability toward being more water-wet without affecting the fluid chemistry of displacing fluids, hence increasing the sweep efficiency by enhancing the displacement of oil by water.…”

Given recent moves towards cleaner energy production, the application of environmentally friendly methods for EOR is considered to be an important research strategy in increasing oil production from existing hydrocarbon reservoirs. Therefore, in this paper, the application of a magnetic field is introduced for the first time as a novel and eco-friendly EOR technique for oil-wet carbonate reservoirs.The magnetic field is generated using three different magnet strengths of 3000, 4100 and 6000 Gauss (G). The impact of incremental increases in magnetic field on oil production from Austin chalk is investigated through measurements of contact angle, rock compaction and the spontaneous imbibition of water and the monitoring of rock surface streaming potential.Dynamic contact angle measurements on oil-wet chalk surfaces in the presence of a magnetic field show that the value of contact angle is reduced faster than when a magnetic field is absent, indicating a significant increase in water imbibition into rock pores. The results of spontaneous imbibition tests reveal significantly greater oil production during the imbibition process in the presence of a magnetic field at about 8.5 times that from oil-wet chalk.Monitoring of the streaming potential of the oil-wet rock surface in the presence and absence of a magnetic field indicates that a change in surface potential charge is responsible for the change in wettability of the surface from oil-wet to water-wet, hence improving water imbibition into carbonate rock which, in turn, can improve the oil displacement from pores.

“…Research showed that the HP treatment enhanced van der Waals interaction by reducing the C–C bond lengths, which led to molecular aggregation ( 34 , 35 ). The molecular aggregation reduced the surface tension of the liquid ( 36 , 37 ), thus enhancing the volatilization ( 38 , 39 ).…”

IntroductionThe flavor deterioration blocks the development of melon juice.MethodsThe effects of ultra-high temperature (UHT) and high pressure (HP) treatments on the aromatic compound concentrations of melon juice and their mechanisms were explored with fresh juice as the control.ResultsA total of 57 volatile compounds were identified by gas chromatography-tandem mass spectrometry analysis. β-ionone was shown to be the major aromatic component of melon juice for the first time. The HP at 200 MPa for 20 min increased the total volatile concentration of melon juice by 1.54 and 3.77 times the control and UHT, respectively. Moreover, the sum concentration of a major aromatic component in the HP treatment was 1.49 and 5.94 times higher than that of the control and UHT, respectively.DiscussionThe HP treatment raised the concentration of volatile and aromatic components of melon juice by reducing their surface tension.

“…Because of the above, it seemed worthwhile to conduct additional research on the impact of static magnetic fields on water's evaporation rate and surface tension. The impact of the MF depends on the time, the magnetic position, and magnetic density, as shown in Figure3, the relation between evaporation rate and MF [52].…”

“…Cai et al [51] observed that the magnetic field significantly decreases the surface tension of salty water. Besides, Amor et al [52] lowered the surface tension of saltwater by 24 percent by utilizing a magnetic field under hot climate settings. Likewise, Wang et al [53] observed that magnetic fields decrease surface tension and specific heat capacity.…”

 A complete survey on the factors that affect the performance of solar pyramid stills is explained.  Specific categorization of these factors is suggested.  Solar radiation is the strongest affecting parameter on the pyramid solar distiller performance.  Promising future scopes of work on the pyramid solar still is suggested.Due to the rising demand for treated water, the enhancement of potable water yield technologies, such as traditional solar distillers, is a pressing concern. Solar desalination is one of the easiest techniques for producing fresh water from salt water. It has several benefits, not the least. It utilizes free solar energy. Moreover, it is a simple and inexpensive technique compared to other alternatives. They are, nevertheless, relatively inefficient devices. Many studies have been done to boost the daily output of solar stills by using many active strategies to produce a large amount of evaporation and condensation compared to a basic standard type distiller. The magnetic field (MF) is one of the most important and recent techniques affecting the productivity of the solar still due to its positive impact on the water evaporation rate. The primary focus of the current study is to review the effects of magnetic field approaches on the distillate production, performance, and thermal efficiency of several types of solar distillers. Based on previous studies, the magnetic field is responsible for increasing the partial pressure difference between water and glass cover. The change occurs in the hydration shells of the saltwater, which should enhance the evaporation rate and improve the performance of solar still. Besides, the magnetic field significantly reduces the surface tension of salty water, which leads to increased evaporation. Furthermore, the intensity, direction, position, and magnet sizes of magnetic have a strong effect on the rate of water evaporation as well as the rate of heat transfer.
