摘要

The collision of diesel oil drops ranging from 500 mu m to 950 mu m on an inclined hot stainless steel surface was experimentally observed for the purpose of discovering the contrast between the collision behaviors of diesel drops and those of other liquids. The experimental results may improve the understanding of fuel drops impact characteristics. Results showed that the critical Weber number for disintegration was very different from the criteria presented by previous researchers for other liquids. The resident time on the hot surface was found to be independent of the impinging angle and normal impinging velocity, and about 30% higher than the free oscillation prediction. An empirical correlation of non-dimensional resident time was built up as a function of the normal Weber number alone. Also, an approximation based on a simple energy balance was presented for the maximum spreading diameter. These two approximations were in a good agreement with the experimental data.
