| Summary: | The problem of temperature distribution in heat exchanger tube sheets was investigated from three aspects, (a) a theoretical analysis of tube plate temperatures (b) an investigation of tube entrance length heat transfer coefficients under conditions of high turbulence and relatively high temperature, (c) an experimental confirmation of the applicability of the method of analysis. Results may be summarized as follows: (a) The approximate method of temperature analysis shows good agreement with more exact methods. A cooled and protected tube sheet for high temperature service was analyzed by the technique. (b) A correlation was obtained for heat transfer in turbulent now in the entrance length of tubes which predicts much higher coefficients than those formed by other workers. Reasons for this were advanced. |
