Two Phase Flow Patterns and Boiling Heat Transfer in Tubes Containing Helical Wire Inserts --Part II - Critical Heat Flux Studies
要約
Critical heat flux (CHF) experiments with refrigerant 113 were conducted in a vertical round tube using two different helical wire inserts. The data indicated the critical heat fluxes to be significantly above those seen in smooth tubes over an appreciable velocity range. The mass velocity at which CHF enhancement is first observed appears to coincide with the onset of swirling flow at the periphery of the heater tube. Based on the present and literature data, a tentative correlation is suggested for the degree of CHF enhancement under subcooled conditions.
