Simulation and analysis of fluid-heat coupling field in the canal based on FLUENT
The phenomenon of uneven temperature distribution in the flow field and unstable wind pressure in the spinning tunnel can easily lead to the phenomenon of splashing on the surface of the fiber tow in the preparation process of acetate fiber tow.Using FLUENT numerical simulation analysis of the method of coupled analysis of temperature,pressure,flow within the channel,the work-ing conditions include 2 different temperatures of hot air flow inlet,1 recovery of cold outflow,slurry inlet and outlet,simulation and optimization results show that:when the hot steam inlet temperature of 88 ℃,the speed of 3 m/s;cold air inlet temperature of 50℃,the speed of 2.7 m/s,the stability of air flow within the channel,uniformity effect is better,which can effectively improve the surface quality of the silk bundle and reduce the flying flower.
