Web27 nov. 2013 · Meredith wrote in his paper that the thrust developed by the system would be greatly increased if exhaust gasses were also vented in the ducting, somewhere after the radiator. The exhaust pipes of an F1 car are inside the ducting so the exhaust system does increase the effect, but the gasses exit outside the sidepods.

At best, it merely offset some of the drag. In-game this is modeled by simply having the radiator produce very little drag even if fully open, regardless of the actual radiator temperature. 3. level 1.

WebMeredith's study of this cooling problem had two components. The first was that drag could be reduced if the cooling air could be slowed before it reached the radiator/fins. The … WebMeredith Effect is taking advantage of an open Brayton Cycle. To achieve a Brayton Cycle you need to compress, heat and expand your fluid in this order. Compressing and expanding is important, because otherwise you couldn't exploit your increase of enthalpy (heat energy) for the sake of thrust. You'd overexpand the fluid at the radiator exit.
