What are the Properties of an Ice-Water Slurry?

[Claws]

Hi - I'm trying to set up a small calculation comparing running glycol/water vs ice slurry, water/ice ratio not known yet but initially why not 60/40, in a closed loop.

However, a quick search on google does not clarify much on the properties of an ice/water slurry, as far as I can tell, the 'rheology' of said matter is not that well understood.

Are there such a thing as approximated numbers for Cp, viscosity etc. for a ice-water slurry?

A colleague of mine suggested using slurry in a cooling loop, instead of glycol-water, and I'm just trying to run the initial numbers - don't come down on me too hard :)

Thanks in advance

.There is certainly some research out there on the properties of ice-water slurries, though it can be difficult to find and interpret. Generally, the viscosity of an ice-water slurry increases with increasing solids loading (amount of ice in the water) and decreases with increasing temperature. Additionally, the specific heat capacity of an ice-water slurry increases with increasing solids loading, but decreases with increasing temperature. As far as exact values, it depends on the precise composition of the slurry, so you may need to conduct experiments to determine these values.
