THERMAL CONVEXITY OF HEAT EXCHANGERS

SINOPSIS
In this paper, a recent steady state method based on the thermal convexity of the heat exchangers is investigated. This method is based on the assessment of the steady state convexity coefficients for both fluids along a tubular heat exchanger. Analytical expressions of the thermal convexity coefficients for both fluids are presented. These coefficients are assessed for different values of the thermal rate ration. This method gives a complementary approach to the well-known procedures for sizing and rating heat exchangers in industrial applications like LMTD and ε-NTU methods.
