Application of Ultrasonic Atomization on a Micro Jet Engine Using Biofuel for Improving Performance

Abstract

Jet engines are commonly used in aeronautical applications, and are one of the types of gas turbine engines. The circulation of air releases heat energy to expand the volume of hot fluids and impact the turbine wheel to generate power of hot gases. The present study investigates the potential of using ultrasonic atomization technology to assist in the combustion process. An experimental rig was set up to determine the performance of jet engines using ultrasonic droplets. A gas analyzer was used to measure various greenhouse emissions of exhaust gas. The performance of the engine was tested under three load levels (high, medium, low), starting from 10 psi at a steady state, to the minimum value. A significant result was tested for a low value of nitrogen monoxide at the three levels of load, and a specific result was tested for an efficiency value of 2% at the three levels of load. Carbon dioxide was found to decrease at the low load level. The use of an ultrasonic atomization device to assist in the combustion process was useful in achieving engine efficiency of 1% and a reduction of 25% in carbon dioxide exhaust gas.

Secondary ultrasonic atomisation mechanisms

“…Ultrasonic atomisation of liquids is widely used in industrial applications such as fuel combustion [1], emulsification of nanoemulsions [2], spray cooling [3], wet dust removal [4] and air humidification [5], spray pyrolysis [6], improving the efficiency of existing gas cleaning equipment [7], etc. The advantages of ultrasonic atomisation over other methods are the high dispersibility of the resulting droplets with a narrow size distribution, which is important especially in medical, chemical and pharmaceutical applications [8][9][10].…”
