Oleg Egorov, a graduate student at the Faculty of Radiophysics led by Professor Olga Voitsekhovskaya, develops methods for diagnosing exhaust gases emitted during the operation of jet engines, volcanic eruptions, industrial work, cars, and other activities. This will help to determine the quality of fuel and to prevent technology-related and natural disasters in the real-time mode.
The scientist is working with a spectrum of hydrogen oxide, carbon, sulfur, and nitrogen - molecules of these gases are formed during combustion of fuel and also during oxidation processes in nature.
- If the number of sulfur dioxide molecules in the gas streams issuing from the volcano increases, the probability of eruptions increases; by fixing this, we can prevent a disaster - said Oleg Egorov. - Similarly, we can judge the quality of fuel, such as aviation kerosene. There are valid standards of concentrations for gas combustion products. If the exhaust gases do not match them, it means that the aircraft cannot fly, otherwise, a crash may occur.
The scientist said that the interaction of exhaust gases with water vapor contained in the air forms acid rain, so continuous monitoring of emissions is important for solving environmental problems.
Now Oleg Egorov is developing physical and mathematical models that describe the spectrum of absorption of the gases. This is the length and intensity of optical radiation after passing through the exhaust gas molecule. He examines the spectrum of absorption in the range from room temperature (296 K) to high temperatures (1000 K) for single gases and their mixtures.
The methods developed by the TSU scientist can be used in the creation of a device that remotely registers the spectral characteristics of exhaust gases and determines the quality of automobile fuel and the operation of industrial plants and jet engines, among other things.
