The Meredith Effect is a term for the use of the hot air from a radiator to provide thrust in aircraft engines.[1][2]

The concept was devised by Fredrick Meredith at the Royal Aircraft Establishment (RAE), Farnborough, prior to World War II, and incorporated into a radiator-duct design that produced thrust, helping to offset the drag produced by the radiator.

One of the first aircraft to incorporate a radiator designed to make the use of the effect was the Supermarine Spitfire.
