Possible Contractions among the System-Describing Parameters

Possible Contractions among the System-Describing Parameters [Pg.238]

In addition to looking for simple relationships that may exist between the burn-out flux and the system-describing parameters, the possibility also exists of trying to find a simplification in the form of a contraction in the number [Pg.238]

for a given P, G and Ah, the hypothesis will be correct if two tubes of different length, but with the same Ljd ratio, give the same burn-out flux. Barnett (B3) has tested Eq. (2), and Fig. 21 gives one of his test results, showing that the hypothesis is not generally valid. Thus, any burn-out theory or correlation which combines L and d only as a ratio cannot generally be correct. [Pg.239]

The above method of testing an hypothesis has proved a very effective tool in burn-out analysis, and has been a great help in appraising the many burn-out theories and correlations that have appeared in the literature. [Pg.239]

Equation (2), for instance, represents several such correlations, including the well-known Bettis correlation (D2) which is probably better identified as [Pg.240]
