Experimental investigation of convective mass/heat transfer in short minichannel at low Reynolds numbers

摘要: Abstract An experimental investigations of convective mass/heat transfer in short circular channel with small inner diameter at Re numbers ranging from 20 to 250 were performed. Mean values mass coefficients measured using electrochemical technique – limiting current method. The results dimensionless coefficient Sh compared conventional theory. It was observed the increase compare data classical correlation relative channels size. heat obtained on basis analogy. Chilton–Colburn analogy applied. effects available literature thermal balance results.
