Performance assessment of triangular Obstacles mounted Solar Air Heater Using Taguchi Method

Abstract

In this experimental work, the investigation about the impact of the geometrical dispositions of the triangular obstacles on the performance parameters such as pressure drop and thermal efficiency. A number of input parameters affects the performance of the system. These input parameters are the heat flux, mass flow rate ( = 0.01 to 0.02 kg/s), obstacles’ height, h from 22 mm to 37.5 mm, their cross-stream wise pitch (Ly = 56 to 206 mm), their angle of inclination with the vertical plane (Θ = 30⁰ - 90⁰), and stream wise pitch (Lx =30 to 70 mm). Moreover, an optimum set of input parameters is determined using the statistical modeling of the operating conditions by the Taguchi technique.
