We were not aware of some errors made in the proofreading phase; therefore, we wish to make the following corrections to the mathematical equations in the text in [1].
(1)
Figure 14 shows that the volume fraction of gasoline at 6 s to 9 s was less than 1%. The distance between the two interfaces with 99% and 1% forward batch concentration is defined as the length of the contamination. Equation (9) can be modified to yield
C = 9 [ 0.21 ln ( N ) + 0.96 ] V
(2)
When the Reynolds number was larger than the critical Reynolds number of contamination, the formula for calculating the contamination length is
C = 11.75 d 0.5 L 0.5 Re 0.1 + 9 [ 0.21 ln ( N ) + 0.96 ] V
