Definition

EN

efficiency of heat transfer by a fluid, expressed by

B e S = S ( Δ T ) S ( Δ T ) + S ( Δ p ) ; where

S ( Δ T ) :: is entropy generation contributed by heat transfer, and

S ( Δ p ) :: is entropy generation contributed by fluid friction

FR

efficacité du transfert de chaleur par un fluide, exprimée par:

B e S = S ( Δ T ) S ( Δ T ) + S ( Δ p ) ; où

S ( Δ T ) :: est l'entropie générée par le transfert de chaleur; et

S ( Δ p ) :: est l'entropie générée par le frottement du fluide
