When I compile your MWE, I get both references printed, but the second 
reference is garbled and causes a warning message in the LaTeX log. It 
appears that the citation was copied from a PDF file and pasted into the 
BibTeX database (either directly or through a program such as JabRef). 
If you open the .bib database in a plain text editor and cursor through 
the title of the Tian & Ahmad paper, you'll see that the first two 
letters of "flows" count as one character (due to kerning in the PDF 
file). Similarly, the two f's in "different" are actually one character.

There's probably a smarter way to fix it, but all else failing you can 
run through the database and retype anything that generates a complaint 
in the LaTeX log.
