BUBRMUL<br />

brl<br />

a keyword which initiates the user flexibility input table <strong>for</strong> the time<br />

dependent coolant flux as a function <strong>of</strong> AT=,, where AT,,, is the degree <strong>of</strong> ~<br />

subcooling. This keyword is followed by “nhb” pairs <strong>of</strong> “dtsat” and “bflx.”<br />

the temperature difference between coolant and saturation, At,a,. (K)<br />

the coolant heat flux table entries. (W/m*)<br />

a keyword which initiates the user flexibility input table <strong>for</strong> the time<br />

dependent multiplier on the calculated coolant flux as a fimction <strong>of</strong> ATM,.<br />

This keyword is followed by “nhb” pairs <strong>of</strong> “dtsat” and “bmul.” The “dtsat”<br />

input is described above.<br />

the table entry <strong>for</strong> the multiplier applied to the calculated coolant heat flux.<br />

the minimum film boiling temperature. (K)<br />

the critical bubble size <strong>for</strong> entrainment. (m)<br />

the multiplier applied to the calculated entrainment rate,<br />

the multiplier applied to the calculated droplet settling flux.<br />

the multiplier applied to the condensed phase diffusion coefficient.<br />

the multiplier applied to the vapor phase diffusion coefficient.<br />

the multiplier applied to the condensation rate coefficient.<br />

the mean aerosol particle size. Default = 1. (pm)<br />

a keyword which initiates specification <strong>of</strong> the following three bubble size<br />

multipliers. The multiplier is used based on the appropriate regime.<br />

the multiplier <strong>for</strong> the bubble size calculated with the Fritz bubble model.<br />
