Resumo

This report deals with the relationship among critical heat flux, flow pattern and flow fluctuation. Under constant inlet velocity, as the exit steam quality increased, the critical heat flux qc does not decrease uniformly, but has a minimum value in the comparatively low quality region. Such tendency was analyzed by using a slug flow model. Moreover, when some compressibility exists in a flow system, flow fluctuation occurs at the entrance of the test section, and qc decreases by the effect of such entrance flow fluctuation. The method to predict the decreasing rate of qc was suggested.
