Development of a Technique for Calculating the Temperature of the Multi-Fuel Nozzle Inner Wall in order to Prevent Sedimentation and Overheating

The article presents the results of a theoretical study on obtaining the formula for calculating the temperature of the inner wall of the multi-fuel nozzle cooling jacket. The problem of overheating these nozzles, as well as the formation of carbon-containing deposits in liquid hydrocarbon fuels and coolants, is discussed. The different ways of dealing with sediment formation, including cooling the fuel channel wall to 373 K are considered. In the case of multi-fuel nozzles, several fuels and coolers can be effectively used at once. The properties of some coolants, including TS-1 kerosene and natural gas, have been investigated. Based on the obtained formula for determining the temperature of the multi-fuel nozzle cooling jacket, a theoretical calculation of the internal temperatures of nozzles of the same mass with several coolants was carried out. An analysis of the results of a theoretical study showed that multi-fuel nozzles are cooled better than single-fuel nozzles and allow predicting fuel consumption in order to achieve the required wall temperature, prevent overheating and sediment formation.
