塑料吹膜机均流板位置对排气影响的仿真研究
Simulation study on influence of position of homogenizing plate in plastic film blowing machine
摘要
Abstract
This study reported an investigation on a specific model of a blown film machine,considering the coupled interaction between its internal wind field and temperature field.A three-dimensional finite element model of the wind field was developed to analyze the characteristics of both the wind and temperature fields.Additionally,the re-search examines how the positioning of the flow-equalizing plate within the machine influences the pressure,veloci-ty,and temperature distribution at the air outlet.The results indicated that increasing the height of the flow-equaliz-ing plate led to minimal changes in the average pressure and velocity at the air outlet,with both parameters exhibit-ing a slight upward trend.Furthermore,the velocity distribution across the air outlet between static pressure boxes demonstrates an initial trend toward uniformity before transitioning to dispersion.Notably,the position of the flow-equalizing plate has negligible impact on both the air outlet temperature and the velocity distribution within individual static pressure boxes.关键词
