Abstract
The combustion of a liquid fuel is a phenomenon with a phase transition from the liquid to the gas. We are proposing to the phase transition is promoted by applying the microwave and assist combustion. The coaxial heating device that can irradiate the microwave directly to the liquid is made, and the temperature distribution when the microwave was irradiated to the liquid was examined. This time, the rise in heat at position at 2mm from center of fuel chamber by using six thermo couples is measured and the difference of the measurement result is examined.
