THERMAL BEHAVIOR OF DIFFERENT FLUIDS IN ELECTROMAGNETIC INDUCTION

Abstract

In this study, the thermal behavior of different fluids in electromagnetic induction heating was investigated. Induction coil, heat exchanger and control circuit designs were made for the research. An experimental setup was created by using a temperature gauge, tachometer, DC motor and circulation pump. The thermal behavior of 650 ml of boron oil, pure water, olive oil, sunflower oil, motor oil and boron – pure water composite fluids after their circulation at 700 rpm and 92 minutes from the experimental setup was investigated. The heat exchanger surface temperature, circulation pipe temperature, beaker temperature and ambient temperature were recorded. The heat exchanger surface temperature, circulation pipe temperature, beaker temperature and ambient temperature were recorded. The specific heat capacity values of the same fluids were also calculated. At the end of the research, it was observed that the temperature of 92 minutes under the same electromagnetic induction and ambient conditions showed values between 79 °C and 95 °C. It has been determined that the most efficient fluid is the engine oil, which has a heating value of 37 °C at the 2nd minute, 85 °C at the 42nd minute and 95 °C at the 92nd minute. It was observed that boron oil, olive oil, sunflower oil, boron – pure water composite mixture and pure water followed, respectively. It has been observed that the specific heat capacity values are inversely proportional to the temperature increase of the fluids.
