摘　　要：为改善某纺织工厂细络联车间温湿度的稳定性及均匀性,提出了一种适用于细络联车间的定向均流送风口,并与复合式混流送风口对比。利用ANSYS Fluent软件对不同送风口下限定区域流场进行数值计算,通过速度、温度、相对湿度及其分布偏差系数评价两者送风效果。在此基础上搭建实验台,验证模拟的正确性。结果表明:当定向均流送风口应用在不同设备布置情况下,可通过调节对开式叶片角度进行风量调节,实现相对湿度调节以达到工艺需求;可通过转动均流导板将气流送至目标区域,实现对设备区域的定向送风。复合式混流送风口和定向均流送风口的速度分布偏差系数均值分别为0.2093和0.0889,温度分布偏差系数均值分别为0.0152和0.0083,定向均流送风口送风效果更好。Objective In response to the increasing requirements for steady temperature and humidity control in textile workshops,this study proposes a directional uniform flow inlet to meet the process requirements of different the workshop equipped with spinning-winding unit based on numerical and experimental studies.A comparison of the new air supply effect with the conventional mixed flow inlet is carried out to provide technical guidance for the actual engineering design.Method A combination of numerical simulations and experiments was used to analyze the airflow organization of the directional uniform flow inlet and the conventional mixed flow inlet with different equipment arrangements.ANSYS Fluent was used to simulate the flow field in the defined area of the different air supply outlets.The airflow organization of the different air supply outlets was evaluated qualitatively and quantitatively using velocity,temperature,relative humidity,and distribution deviation coefficients.Based on this,an experimental benchmark was set up to compare the airflow effects so as to verify the feasibility of the numerical simulation in the textile workshop and to evaluate the respective airflow effects using the velocity and temperature distribution deviation coefficients.Results The simulated and experimental results of the temperature distribution for the directional uniform flow inlet showed high agreement with each other,which verified the effectiveness of the numerical model used.In terms of velocity distribution,(Fig.3,4),the directional uniform flow inlet had a more even airflow distribution due to the presence of the split blades,ensuring the airflow range meeting the requirements of the working area.The velocity showed a trend of being lower at both ends and higher in the middle,with a relatively gentle curve.The velocity was higher the winder area than in the spinner area in the model,demonstrating the capability of the new design for air volume distribution for a small environment.In contrast,the conventional mixed flow i
