Experimental investigation of the effects of mass fraction and temperature on the viscosity of microencapsulated PCM slurry

The non-steady state condition was also examined, more specifically, the temperature of the sample was increased continuously at a steady pace from 16 °C to 29 °C. This stage took 17 min with each data point collected at 15 s intervals. During a non-steady state temperature increase, near melting point, the viscosity of the slurry clearly departed from those values observed in steady states. It can therefore be concluded that around the melting point temperature, the phase change process of mPCM slurry influences the viscosity.
