I am a student doing masters project. My topic is Room level air flow modelling for thermal management in data center. I am not getting how to change rack outlet temperature with rack inlet temperature per iteration.
Tout= Tin + (temperature difference) Rack is modeled by black box approach. Model validation is achieved for rack inlet temperatures. For parametric studies with high supply temperatures , higher rack inlet temperatures are predicted. But rack outlet temperature with mass flow inlet boundary condition is fixed for the CFD case. It should change with higher rack inlet temperature for constant temperature difference for a segment between rack inlet and rack outlet. Can user defined function (udf) would serve my purpose.I am doing steady state analysis. Can transient simulation only could have this provision. Also cannot understand a statement mentioned in the research paper for the same. A measured temperature rise corresponding to each segment was imposed in the computational model to simulate the heat generated by the racks. Please Help. |
