Geometrical and operational parameters effect on inline hole jet plate solar Air heater with longitudinal fins for cross and non-cross flow conditions
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 8
Abstract
This paper is based on analytical study of flow and heat transfer in cross and non - cross flow inline hole jet plate solar air heater with fins attached underside the absorber surface. Results are presented for various fixed and variable geometrical and operational parameters such as jet hole diameter D = 6 - 10 cm, pitch of the holes X = 6 cm, number of jet holes, N = 480, height of the longitudinal fins Lf = 0.012m, pitch of the fins p = 3 mm, depth of the lower and upper channel, Z1 and Z2 = 8.0 cm, mass flow rates of air ṁ1= 50 to 300 kg / hm2 whereas ṁ2 = ṁ1/2for cross - flow and ṁ2 = 0 for non - cross flow, solar intensity IT = 650 W/m2 , wind velocity Vw = 1.3 m/s and ambient temperature TA = 30oC. The results show the To and hPj are higher in non - cross flow than cross flow condition whereas ηc is higher in cross - flow than non - cross flow than cross flow condition under same geometrical and operational parameters
