In order to avoid being gunned down by a sentry gun (especially one placed in the corner of a room), I often try to hide around corners, fire my flamethrower and gradually "worm my way in" to destroying the sentry. However, I often wonder: is this necessary? Could I simply stand around the corner and shoot flames?

The reason that I am uncertain about the answer is that, sometimes, when I blast my flamethrower around a corner, it almost "repels" against the corner of the wall, e.g. here: and, other times, it goes through the wall, e.g. here:

In either of these cases, would the flamethrower do damage to, say, a Sentry in the corner of the wall (roughly where my flamethrower is aimed)?
