Table 2 presents results of simulation calculations for the cold(water) side. Conditions #1–4 simulate those near the water inlet of the heat exchanger; conditions #5–8 resemble those near the outlet. Hot (CO2) side results are presented in Table 3. For the hot side, #1–4 are results near the inlet of CO2, #5–8 are those obtained near the outlet, and #9–12 are near the pseudo-critical point at the pressure. Nusselt quantities of each result were calculated as follows. The heat load is obtained as Eq. (1),
