Summary

The paper shows that the transient time of convection is a function of centrifugal acceleration and is proportional to the -1/3 power of it. Also, a remarkable phenomenon, which is referred to as a "bubble cluster bridge" and which has not been observed in the stationary experiment, occurs at the beginning of heating. A new type of optical sensor is applied to measure the transient phenomenon of convection as an auxiliary observation. The bubble departure time from the heater surface is also proportional to the -1/3 power of centrifugal acceleration.
