摘要：

An investigation on the post-CHF heat transfer in a electrically heated coil with horizontal helix axis is reported. The wall temperature varies with different circumferential locations, having a higher value at the inside surface (the suxface closest to the coil axis).Based on the experimental results, the correlation of post-CHF heat transfer coefficient of the coil is obtained. The average heat transfer coefficient is larger with the coil than with straight tubes.
