Paper No: IMECE2021-72603
... in the rate of reaction and therefore limits the maximum current density achievable by the cell. A degassing channel concept is investigated in this study to collect Carbon dioxide bubbles and keep them away from the main channel. A 3D two-phase flow model is developed and validated to investigate bubble...

Proc. ASME. IMECE2019, Volume 8: Heat Transfer and Thermal Engineering, V008T09A013, November 11–14, 2019
Paper No: IMECE2019-10272
...Abstract Abstract Two-phase refrigerant pumped loop cooling systems have seen wider use in recent years because of higher power density electronics and the need for increased heat transfer capability. However, two-phase systems are difficult to model because they operate in a closed-loop...

Paper No: IMECE2012-86274
... Hydrodynamic and thermal characteristics of Al 2 O 3 – water nanofluid flow at entry region of a uniformly heated pipe are studied applying finite control volume method (FCV). Single phase and Eulerian-Eulerian two-phase models were used in modelling of nanofluid flow and heat transfer. The two...
