In thermal transient analysis, time-dependent values of the bulk temperature and convection coefficients must be described as functions of time within the corresponding Thermal Software. Describing Time-Dependent Values as Functions Bulk temperature may ramp up and down slowly, whereas water flow rates may change quickly as pumps go on or off, or as valve positions change. The bulk temperature of the water may change at times that differ from times at which the flow rate changes.
Consider the example of both water temperature and flow rate in a pressure vessel changing over time. When performing a time-transient thermal analysis in FEA, it is common to have bulk temperature loads and convective heat transfer coefficients that change values during the transient.
