| Abstract: | Based on theoretical analysis and comparison, a new expression of non-depositing critical velocity was proposed and has been verified with those published experimental data by comparison with other existing formulas. It is found that the new formula can be used for predicting non-depositing critical velocity with an average error less than 15%. |
