The University of St Mark and St John student will compete in her favourite event, the one-metre springboard, first. Gayle is four-time British champion in that discipline.
The prelims will take place in the morning with the semi-finals five hours later. The final will be held on Saturday.
Gayle will also compete in the three-metre springboard event, which is scheduled for Tuesday and Wednesday.
Her club and university team-mate Robyn Birch is also competing for Great Britain in Gwangiu.
Birch, fresh from her synchro medal-winning display at the European Championships, will take part in the individual platform event on Saturday.
However, for Gayle this is her biggest event of the year.
“To go out there and compete is an amazing opportunity,” she said. “I’m so grateful to be picked for it.
“I’m looking to enjoy the competition. It will be the first time I have competed on the world stage.
“I am just going to go out there and look to put on a good performance and see where it goes.”
Former Plymouth College pupil Joe Patching will also be competing in the swimming for Great Britain in Gwangi.
