By using a specially designed probe mechanism which entered the system through the pipe outlet and which could be located quite accurately at any radial or longitudinal position in the pipe an extensive set of measurements was made of the temperature profiles in the heat-transfer entry section of an
Ahstraet-Turbulent temperature profiles and heat transfer coefficients have been measured in an electrically heated 2 in. i.d. pipe with a +X t in. spiral rib of pitch/dia ratio 2.58. Rifling resulted in greater than twofold increases in Stanton number St, but with a proportionate increase in fricti
