Determination of heat transfer coefficients during in-tube gas cooling of supercritical carbon dioxide.

Author(s) : ROBINSON D. M., PITLA S., GROLL E. A., RAMADHYANI S.

Summary

In order to use carbon dioxide, new components must be designed. In fact, the entire heat rejection process may take place above the critical temperature and pressure. Hence, the design of the heat rejecting heat exchanger requires knowledge of carbon dioxide transport properties associated with temperatures and pressures above the critical point. A test apparatus built exclusively for the experiment is being used to quantify the local heat transfer coefficients as well as pressure drop. In addition, the test stand is being used to investigate the action of compressor oils and the in-tube surface enhancement.
