Temperature and airflow distributions around heated pans by a gas-oven and an IH-heater were compared, and the difference in steam generation was studied. As a result, we found that the existence of flame around a pan affected the airflow and the temperature distribution, etc. We also found that water evaporated by IH-heaters was more easily changed into mist. The number concentration and the size distribution of water mist were measured using a PDPA system. The number of water mist generated with the IH-heater was 10 to 100 times larger than the number of mist generated with the gas-oven. The mode diameter of mist generated with the IH-heater was 8 to 10 μm, and that with gas-oven was 4 to 5 μm. We concluded that the mist size difference resulted from the difference in temperature distribution and the existence of hot flame around the pan in the case of gas-oven.
