Varmeovergang og trykfald ved fordampning af kuldioxid (Heat Transfer and Pressure Drop for Boiling Carbon Dioxide)

Heat transfer and pressure drop for carbon dioxide, pure and mixed with oil, has the been measured for flow in pipe. The measured heat transfer coefficient for pure carbon dioxide is much higher than the value calculated with the Shah correlation. With oil even higher heat transfer coefficient has been measure (less then 2.6% olil) The measured pressure drop is within 25% of the value calculated with Bandel-Schlünders correlation.
