description abstractExperimental data on the variation of the point unit thermal conductance in the entrance section of a circular tube are presented for 16 different flow conditions of the entering air. Results are compared with values calculated from existing analytical solutions.
The average (integrated mean with length) unit thermal conductance is also calculated for eight entering-air conditions and is compared with values resulting from analytical methods. In many cases the experimental values are appreciably higher than those derived from equations which are based on over-all taken on long pipes.
