The cooling efficiency of s-CO₂ microchannel heat sink compared with a water-based design

High-pressure drops characteristic of microchannel heat sinks (MCHS) is an issue that needs to be addressed to reduce the size of heat-removing devices in compact electronic devices. Supercritical carbon dioxide (s-CO₂) is a suitable candidate being proposed as an alternative coolant to enhance the cooling of the microchannel heat sink (MCHS)...

Erosion Estimation for the Impeller Blades of Centrifugal Dredge Pumps

The constant impingement of sand particles on the wetted surfaces of a centrifugal dredge pump causes the performance of the pump to deteriorate. Therefore, components or complete pumps have to be replaced after some time. The use of numerical models to estimate the erosion wear in centrifugal dredge pumps can give insight into the principal...

Numerical investigation of the flow field and mass transfer characteristics in a jet slurry pump

A jet pump is used to transport a variety of working media and is especially suitable for dredged soil transporting. In this study, a three-dimensional numerical study of a jet pump that is used for slurry delivery was carried out. The characteristics of the internal flow field of the mixing chamber with different working parameters were...
