正反包波纹板是常见的板式空气预热器传热板片型式。通过数值模拟的方法,采用与正反包波纹板特性相似的标准圆柱绕流周期性模型,研究了圆柱排布间距l与圆柱流道直径d的比值l/d对模型阻力性能的影响。研究结果表明,当l/d逐渐增大时,其对阻力性能的影响逐渐减弱。当l/d≥5.2时,压力损失对l/d数值的敏感度明显降低。以标准圆柱绕流周期性模型研究结果为参考,优化设计出了阻力性能满足工况要求的板间距3 mm、波纹间距75 mm的正反包波纹板。

The double-dimpled plate is a common type of heat transfer plate for plate air preheaters. Through a numerical simulation method,a standard periodic cylindrical cross-flow model with similar characteristics to the double-dimpled plate was used to study the effect of the l/d ratio of the cylinder spacing l to the diameter d of the cylindrical flow channel on the resistance performance of the model. The study found that as the l/d ratio gradually increased, its effect on the resistance performance gradually weakened. In particular,when l/d≥5.2,the sensitivity of the pressure loss to the l/d value decreased significantly. Based on this conclusion,a double- dimpled plate with the plate spacing of 3 mm and the corrugation spacing of 75 mm was designed and optimized to meet the performance requirements.
