Enhancement of critical heat flux in tubes using staged tangential flow injection

Technical Report · Sun Dec 31 23:00:00 EST 1989

OSTI ID:6242324

Significant enhancement in critical heat flux in tubes is possible by tangential injection of liquid. The enhancement depends on the ratio of momentum rate of the injected fluid to the momentum rate of the fluid exiting the tube, the tube length, injector to tube diameter ratio and on the density ratio of the liquid and vapor. In the reported experiments, critical heat fluxes as high as {vert bar}kw{vert bar}cm{sup 2} were obtained with up to about 50% enhancement over that for purely axial flow. 12 refs., 18 figs., 4 tabs.
