Experimental investigation has been conducted on a collector for non-cross flow configuration. The structure incorporates fins with impinging air jets below the absorber surface. The main aim is to examine the significance of implicating both the methods on heat transfer and thermal performance of the apparatus. Testing covers a prescribed range of operating and geometrical parameters such as, fin spacing (w = 0.03 and 0.06 m), stream-wise pitch (3 cm and 6 cm), dimensions of jet (circular in shape having diameter (D_j) = 6 mm, 8 mm and 1cm), mass flow rate of air (ṁ = 0.056–0.112 kg.s^-1) and (Re= 5700–11700) respectively. An appreciable augmentation in thermal performance is noticed by mutual use of fins and air jets. The experimental data collected is further processed to develop correlations for Nusselt number in conjunction with fin and jet parameters of the set up for both the techniques separately.

带有冲击空气喷射式太阳能空气加热器的鳍片的相关性

已经对用于非错流构造的收集器进行了实验研究。该结构在吸收器表面下方结合了带有冲击空气射流的散热片。主要目的是研究将两种方法都牵涉到设备的传热和热性能的重要性。测试涵盖规定的操作和几何参数范围，例如，翅片间距（w = 0.03和0.06 m），沿流方向的螺距（3 cm和6 cm），射流尺寸（具有直径（D _j）的圆形）= 6毫米，8毫米和1厘米），空气质量流量（6 = 0.056–0.112 kg.s ^-1）和（Re = 5700-11700）。散热片和空气喷嘴的共同使用可显着提高热性能。收集到的实验数据将被进一步处理，以结合两种技术分别设置的鳍片和射流参数来开发Nusselt数的相关性。
