Ghosal, world ranked 21st, will take on the local challenger Tamimi, ranked 209th in the world, at the Khalifa International Tennis & Squash Complex tomorrow.
Another Indian in the fray, unseeded Siddharth Suchde will lock horns against Germany's Simon Rosner in the first round.
This week's PSA World Championship will provide one of the most dramatic climaxes to the end of a PSA World Tour year ever - with four players in reach of the first world number one ranking of the New Year 2013.
Furthermore, four different players will be out to consolidate their positions in the top eight of the Dunlop PSA World Series Standings in order to confirm their places in January's flagship ATCO PSA World Series Finals in London.
Meanwhile, a further four will be looking to stage late bids to join the World Series Finals field by battling through to at least the World Championship semi-finals.
And, finally, England's Nick Matthew will be looking to defend the sport's premier title he won for the second time in Rotterdam in 2011 - and become the first player since Pakistan's legendary Jansher Khan to claim the trophy three times in a row.
Boasting a USD 325,000 prize fund - the second biggest in the sport's history - the premier event on the PSA World Tour will reach its climax on December 14.
