摘要
采用CFD方法对圆形喷口单股等温自由射流进行数值模拟研究,提出了一种新的用于风口模拟的盒子分区计算模型。先将计算结果与Elsaadawy(1998)、Hussein(1994)实验数据和经典射流公式进行对比,选定合适的湍流模型,后通过对盒子分区计算模型的结果分析对比,说明该模型的可行性,为复杂风口大空间流场计算提供了一种新的思路。
Using CFD method to study the isothermal round jet, a new partitioned box method for simplified air supply opening model was proposed. Firstly, Compare the results with Elsaadawy（1998） Hussein（1994） experimental data,and then compare with the classic jet formula, select the appropriate turbulence model. Secondly, through contrast the result of partitioned box method with basic model, certifying the reliable and feasible of this model, provided a new way to forecast the complex air flow in a large space field.
