Grooved flow pattern

If the thermocouple wires are located in a hole or groove in a metal tube or plate, the fin effect will be remedied, but the heat flow pattern through the solid will be altered. The correct surface temperature can be computed by the relaxation method. This corrected method has been used for boiling studies (S2), but many workers have made no correction for embedded wires. 

M 80] [P 70] Cross-sectional images of the flow patterns, gained by confocal microscopy, demonstrate the interfacial stretching and hence are indicative of mixing in the barrier-embedded mixer [58], At the non-barrier entrance structure clearly the helical flow induced by the slanted grooves is evident. In the barrier...
