In real-life cooling packages there will be an non-uniform air flow distribution on heat exchangers, which can have a big effect on heat transfer rate. Using CFD results with KULI it is possible to consider this uneven air flow on heat exchangers.
In the KULI direct CFD interface method *.txt-files containing a velocity distribution from CFD calculation and *.txt-files for writing output like a temperature distribution have to be defined. Unlike the standard/variable resistance matrix method, the direct CFD interface does not require the preprocessing step of calculating a matrix of local resistance corrections. Also unlike the two other methods, here the influence of fans or cp-values on the system air flow are neglected, the system airflow is taken directly from the velocities of the CFD input file. The big benefit of this method is, that KULI can be directly integrated in CFD code, e.g. for iterative underhood computation.Usable from release: KULI 8.0-1.04
