| Abstract: | According to the experiment and numerical simulation, the temperature field and its variation law of acetone and the tiny metal grains are studied under the transient and extremely high heat flux condition, while the platinum film resistance is overlaid with tiny metal grains or nothing. The speed of temperature rise, temperature grads and the thickness of heat layer are calculated numerically. Some stranger phenomena that are different from abnormal boiling are observed. It points out that it is easy to get higher speed of temperature rise while the platinum film is overlaid with nothing than with tiny metal grains despite of its vehemently boiling behavior. |
