| Abstract: | In
this paper, a local simulation method is employed to investigate the heat transfer and
pressure drop characteristics of several kinds configuration pin-fin casing tube heat
exchanger unit. The empirical correlations of heat transfer and flow friction loss for gas
longitudinal flow to these pin-fin casing tube are obtained.On the basis, the experimental
results of different configuration parameters for these pin-fin casing tube are anaysed
and the effects on heat transfer and pressure drop for commonly used pin-fin geometry and
pitch arrangement in pin-fin casing tubes are compared. The results obtained in this paper
can be used in the design of pin-fin casing tube heat exchanger. |
