The double flow turbine design not only provides double the expansion volume within a common casing, it also balances the large pressure drop between the turbine steam inlet and exhaust which tends to force the blade wheels from the high-pressure side towards the low-pressure side. ... Steam enters the turbine in the middle of the casing and expands outward in both directions before exhausting at the ends of the turbine. In each half of the turbine, a very large thrust is generated. These thrusts oppose each other; the resultant force is significantly reduced. 1, record 2, English, - double%20flow%20turbine

Premièrement, une turbine à double flux permet de doubler le volume d’expansion dans une seule turbine. Deuxièmement, elle absorbe la forte chute de pression de la vapeur, qui se traduit par une force exercée sur les roues à ailettes depuis le côté haute pression vers le côté basse pression. [...] La vapeur pénètre dans la turbine par le milieu du corps et se dilate vers l'extérieur dans les deux directions, avant d’être évacuée aux deux extrémités de la machine. Chaque moitié de la turbine produit une très forte poussée. 1, record 2, French, - turbine%20%C3%A0%20double%20flux
