keywords FLAG, X, and Y are given in Section 14.4.2. The other keywords and values associated<br />

with FORCED are defined below.<br />

FORCED keyword to specify that a number <strong>of</strong> <strong>for</strong>ced convection tables follow.<br />

nmtb number <strong>of</strong> tables to be used with the FORCED option. The tables are<br />

numbered in the order that they are entered, the first being 1, the second 2,<br />

and SO <strong>for</strong>th.<br />

n the number <strong>of</strong> points in the table.<br />

x the independent variable <strong>of</strong> the table, corresponding to time. Specify “n”<br />

values in ascending order. Note that outside <strong>of</strong> the range <strong>of</strong> times in the<br />

table, the degree <strong>of</strong> <strong>for</strong>ced convection will be assumed to be zero.<br />

VAR-Y<br />

option<br />

keyword to speci@ the type <strong>of</strong> dependent variable represented by the table.<br />

character variable determining the dependent variable in the table. Specify<br />

either VELOCITY, REY-NUM, or NUS-NUM depending on whether<br />

velocity, Reynolds number, or <strong>for</strong>ced convection Nusselt number is specified<br />

by the table.<br />

Y the dependent variable <strong>of</strong> the table. Specify “n” values appropriate <strong>for</strong> the<br />

choice made <strong>for</strong> “option.”<br />

EOI keyword used to terminate each table.<br />

STR-COND keyword to specify the correspondence between the <strong>for</strong>ced convection tables<br />

and the structures. The default <strong>for</strong>ced convection treatment, based on gas<br />

flow path velocities, is used <strong>for</strong> any structure not specified.<br />

nprs the number <strong>of</strong> pairs <strong>of</strong> values <strong>of</strong> “istruc” and “itabl” to follow.<br />

istruc the number <strong>of</strong> the structure associated with the table “itabl.” The structure<br />

number is determined by the order <strong>of</strong> input <strong>of</strong> the structures in the heat<br />

transfer structure input block. Both the inner and outer surfaces will be<br />

assigned the <strong>for</strong>ced convection conditions specified in the table, if both lie<br />

within the cell; otherwise, only the inner surface will be assigned.<br />

itabl the number <strong>of</strong> the table containing the <strong>for</strong>ced convection in<strong>for</strong>mation <strong>for</strong><br />

structure “istruc.”<br />

The following is an example <strong>of</strong> the STR-COND input:<br />
