摘要

Turbulent convection of fluid flow through the impingement round jets solar air rectangular passage with circular inside conical ring obstacle shapes is studied experimentally. The testing of a rectangular solar air passage with round impinging jet contains; relative inside conical ring height (lies from 0.073-0.128, ratio of inlet flow diameter to inner print diameter of ring (lies from 1.3-2.3, ratio of ring diameter to ring height / lies from 1.67-2.67, relative X-axis pitch (lies from 4.71-7.71, relative Y-axis pitch (lies from 2.92-5.14, relative impingement round jets diameter (and Reynolds number (Re) of flow was varied between 5,000 to 23,000. The fixed values of relative impingement round jets diameter (of 0.366, relative X-axis jet distance (of 0.366, and relative Y-axis jet distance (of 0.311 were selected. The highest value of hydrodynamic and thermal performance is observed at of 0.110, of 1.7, /of 2.33, of 5.28, of 3.42, of 0.055, of 0.366, and of 0.311.
