摘要: Nucleate pool boiling experiments were performed using pure R11 for various surface angles under constant heat flux conditions during saturated boiling. A 1-mm-diameter circular heater with an artificial cavity in the center that was fabricated a MEMS technique and high-speed controller used to maintain flux. Bubble growth images taken at 5000 frames per second CCD camera. The bubble geometry obtained from captured images. effects of angle on behavior analyzed initial thermal regions dimensional scales. parameters affected radius, rate, sliding velocity, shape, advancing receding contact angles. These phenomena require further analysis data provide good foundation such future work.
