Specified temperature flux ntime Number of panels in the time-variable, specified temperature flux function. For each panel, enter the following: (a) ton_val, toff_val, bc_val, bc_temp Time on [T], time off [T], specified volume flux (of liquid) [L3/T] multiplied by the heat capacity [J kg−1 K−1] and density [M/L3] of the boundary medium, temperature of water entering [K]. Nodes in both the chosen faces and the currently active media (see Section 5.8.1) are assigned a time-variable temperature flux value. Although a fluid volume flux bc_val is specified, this does not influence the flow solution in any way. It is merely intended to give the user a straightforward way to input a known amount of energy to the system, as a function of fluid volume and temperature. • • • The following instructions are used to define the atmospheric inputs discussed in Section 2.6.1.10, and summarized in Equation 2.121.
