An experimental study of the swirl vane effect on CHF
- 1. KAERI, Taejon (Korea, Republic of)
Description
The effect of rotational flow on Critical Heat Flux (CHF) is experimentally examined using with and without swirl vane grid units in a round tube. In addition, the optimum design of the swirl vane is also investigated with three kinds of vane angles such as 25, 30 and 35.deg.. Refrigerant R-134a is used as the working fluid for the test convenience, since this test is to under stand the relative CHF enhancement due to the existence of a swirl vane in the grid. For the results, the swirl vaned grids always showed better CHF performance than no vane grid within the tested conditions. Among the three vane angles, the 35.deg. swirl vane revealed the highest CHF in most of the cases. Particularly, for the condition of a pressure of 2.6 Mpa and a mass flux of 1500 kg/m2 s (water equivalent to the normal operation condition of PWR) the CHF enhancement is, at least, above 15%
