Dear nContinuing with the simulation, I no longer get the contradicting results but the original problem reminds. nAttached, please find the air volume fraction contour for air flow rate of 0.3 g/s and 5.0 g/s.nRegardless of the air volume, the results are almost the same (CPU temperature and fluid velocity too). nDoes that mean, 5.0g/s of bubbles is still not enough to make any difference?.I am trying to demonstrate that addition of bubbles increases the cooling capacity. nAnd also I aiming to determine the optimal air diameter and air flow rate.Your insightful feedback would be highly appreciated.Best regards,nNatnn
