Due to the large temperature difference between ambient temperature (25 ℃) and the temperature under standard atmospheric pressure and its large sensible heat storage capacity
ethanol slurry can be used as a cold thermal energy storage medium in the cold-chain transportation market. The flow characteristics (particularly the pressure drop) of the ethanol slurry are important parameters in various applications. Combined with the two-fluid model based on particle phase dynamics proposed by Gidaspow
changes in the flow rate and pressure drop of an ethanol slurry flow with solid phase fraction in a horizontal straight pipe were studied using FLUENT. When the flow rate increased from 0.51 m/s to 0.92 m/s
the pressure drop increased from 5.184 kPa/m to 63.707 kPa/m and the solid phase fraction changed from 10.4% to 30.5%. The model was consistent with the experimental observations; the average deviation between the experimental results and the numerical simulation was 12.8%.
