Sorry to be the one to say this but it depends largely on a number of factors such as; your opponent's image at the table, his stack size, time in the tournament, i.e. is it on the bubble or early on.
Try posting specific hands in the correct strategy forums though and I'm sure you will get some good answers.
Generally speaking though you should never fold a set on the flop, even if your opponent shows up with the flush you always have outs for the full house.
