Features of water and water solutions heating under the influence of variable electromagnetic field

In the manufacture of aircraft parts electrochemical and chemical processes with high temperature working liquids are used. Now the use of hot water, steam, electric heaters for heating fluids are not effective. The article presents the experimental setup for hot water and aqueous solutions of AC power frequency. The article describes the method for testing and given expression for calculation of specific electricity consumed and the resulting specific heat density. At low power density ratio of the thermal energy released in the fluid by passing an electric current through it to the amount of electrical energy supplied to the heating fluid is close to unity. The second feature of this process is independent nature of the change ratio of the thermal energy released in the fluid by passing an electric current through it to the amount of electrical energy supplied to the heating fluid, depending on the specific power on the type and concentration of salts in the water. It was found that on heating water and aqueous solutions depends on material electrodes. Thus, the use of the titanium electrode gives higher values of the ratio obtained to the thermal energy consumed electric. It is shown that the contribution of the magnetic field in the heating fluid, located between the electrodes, negligible. The process of heating the water and water solutions is carried out based on independent from each other mechanisms: the electrochemical reactions on the electrodes; heat generation in the electric double layer; by eddy phenomena in the volume of water.
