“…Wang et al studied ice slurry (<25 v/v %) in horizontal, vertical and 90° elbow pipes using the Euler‐Euler model, and found a relative errors of ±20% with respect to the measurements. Ma et al investigated the hydraulic and heat transfer characteristics of PCD in a circular smooth pipe using the Euler‐Euler model, and showed a good agreement with previous experimental results. However, the use of the Eulerian‐Eulerian model to study heat sinks is still limited due to large computation resource demand.…”

The paper concerns with a high performance cooling method for a HVDC converter using fatty acid ester-based phase change dispersion (PCD) in a heat sink with double-layer oblique-crossed ribs. Thermo-physical properties of PCDs were first characterized under both solid and liquid states, and the cooling performance of the heat exchanger was then experimentally examined, by heating two copper blocks clamped closely to the aluminium heating surfaces. A threedimensional Euler-Euler multiphase approach was further performed to evaluate the thermal performance under different operating conditions including heating power, flowrate and PCD concentration. The results showed that the

“…For high power electronic devices, an option for thermal performance enhancement is the dispersion of Phase Change Material (PCM) in an immiscible thermal-active fluid -the so called phase change dispersion (PCD). Under a targeted set of operational conditions, the PCD can be designed to enhance the thermal performance with a uniform temperature distribution and a small temperature change [6][7][8][9].…”

“…Wang et al [36] studied ice slurry (< 25 v/v %) in horizontal, vertical and 90 ° elbow pipe using Euler-Euler model, with a simple and cheap algebraic equation for granular kinetic calculation which neglecting convection and diffusion. The PCM slurry [7] and slush nitrogen [37] were also tested, but the particle distribution on viscous sub-layer (which will affect wall temperature) was easily missed.…”
