On the other hand, the plasma generated by discharge has a very high enthalpy value, can generate disturbance to a gas flow field, improves the turbulence degree of airflow, increases the contact probability of fuel molecules and oxygen molecules, and can enhance the combustion sufficiency. Due to the above advantages of plasma combustion-supporting, it is receiving extensive attention from researchers.
