Figure 5.54 Unheated wall effect on critical heat flux (system parameter concept). Data from Babcock (1964) and Janssen and Kervinen (1963a).

Local parameter concept Styrikovich et al. (1960) studied the length effect on the critical heat flux at a constant exit quality with an 8-mm (0.3-in.) round tube at a pressure of 1,500 psia (10.2 MPa) operating in a stable system. Their measured CHF at various LID values (with accompanying Hm changes) are listed in Table 5.7. This can be considered a demonstration of small length effect and/or Hin effect...
