This quantity collects jointly the lectures and papers awarded on the joint Los Alamos nationwide Laboratory - Commissariat a l'Energie Atomique assembly, held at Cadarache citadel, in Provence (France), April 22-26, 1985. approximately 100 members got here from either laboratories and from different linked French businesses.

Example text

The following example demonstrates such a calculation. Example: A liquid-to-liquid counterflow heat exchanger is used as part of an auxiliary system at a nuclear facility. The heat exchanger is used to heat a cold fluid from 120-F to 310-F. Assuming that the hot fluid enters at 500-F and leaves at 400-F, calculate the LMTD for the exchanger. Solution: T2  400-F  120-F  280-F T 1  500-F  310-F  190-F Tlm  (T2 ln  T 1 ) T2 T1  (280-F  190-F) ln 280-F 190-F  232-F The solution to the heat exchanger problem may be simple enough to be represented by a straight-forward overall balance or may be so detailed as to require integral calculus.

Since the thickness of a condenser tube wall is so small and the cross-sectional area for heat transfer is relatively constant, we can use Equation 2-11 to calculate Uo. Uo  1 h1  1 r k  1 h2 Example: Referring to the convection section of this manual, calculate the heat rate per foot of tube from a condenser under the following conditions. Tlm = 232-F. 75 in. 1 in. Assume the inner convective heat transfer coefficient is 2000 Btu/hr-ft2--F, and the thermal conductivity of copper is 200 Btu/hr-ft--F.

The process of going from nucleate boiling to film boiling is graphically represented in Figure 13. The figure illustrates the effect of boiling on the relationship between the heat flux and the temperature difference between the heat transfer surface and the fluid passing it. Rev. 0 Page 41 HT-02 BOILING HEAT TRANSFER Heat Transfer Figure 13 Boiling Heat Transfer Curve Four regions are represented in Figure 13. The first and second regions show that as heat flux increases, the temperature difference (surface to fluid) does not change very much.
