The oscillatory heat transfer characteristics of supercritical water in vertical upward parallel channels were experimentally investigated under the condition of pressure from 26—30 MPa
time-averaged mass flow rate of 420 kg·m

and heat flux from 0—130 kW·m

. According to the experimental results
the effects of mass flow rate oscillation on wall temperature
oscillatory amplitude ratio (
A
f
) and oscillatory frequency number (
Wo
) on time-averaged Nusselt number were analyzed
and the time-averaged
Nu
of oscillatory flow was compared with the supercritical heat transfer correlation equations. The results show that the wall temperature fluctuates with mass flow rate oscillation at the same oscillatory period and opposite phase
and the larger amplitude of ma
ss flow rate oscillation leads to the stronger fluctuation of wall temperature. At the occurrence of low frequency oscillation
the time-averaged
Nu
decreases with the increase of oscillatory amplitude ratio
and decreases firstly with the increase of oscillatory frequency number and then remains constant. At the occurrence of high frequency oscillation
the time-averaged
Nu
increases slowly with the increase of oscillatory amplitude ratio
and decreases with the increase of oscillatory frequency number. The values of
Nu
predicted by correlations is generally higher than that of experiments.
