EXPERIMENTAL STUDY ON WIRE MESH SOLAR AIR HEATER

Abstract

Using Experimental Research, a parametric study was performed of a Wire mesh solar air heater natural convection SAH. For the analysis, a SAH with a single glass cover is selected as a flat plate solar collector with wire mesh Under the DTU Delhi climate conditions, India. The study aims to find optimum collector efficiency and taking seasonal variations into beam radiation and diffused radiation, seeking input and observing the output variable parameter Impact on collector output of incident radiation magnitude and ambient temperature, all equations, the framework, the governing continuity, momentum and energy equations were considered. SAHs have been used for heating, drying, and similar industrial applications which require heating, drying, and other heated air at temperatures that are low to moderate. SAH (collector)’s performance is a feature of many criteria for design and operation. The heat from convective HT coefficient between the Abp and the air due to one of the main parameters is the collector duct. It is possible to use the air on the right side of the Abp of the SAHs for their thermal output. The THeff of a SPSAH with wire mesh was examined only experimentally. A comparison of the effects of solar collector MFRs with and without wire mesh shows a significant increase in THeff. This experiment deals with the Tout 0C and performance of the experimental inquiry, of the WMSAH. The experimental test was planned and manufactured to research the effects of WMSAH, by the axial fan in a solar duct flow, on the wire mesh solar air heater compared to the traditional SAH on a FPC’s Abp, under the effect on the Tout 0C of the MFR of air and SI, results, are analyzed. The findings of experimental research on the Tthp of a WMSAH are provided in this experiment. In direction to maximize the surface of heat exchange, the Tout 0C, and THeff, a black wire mesh for an Abp must be designed in particular. Tables 7.1a show that for the SAH without wire mesh and a black Abp, increases in MFR affect the temperature of the wire mesh and the temperature of an Abp by 5 to 6 0C. By rates of 5.3 percent and 6.13 percent, the THeff of the type with WMSAH is shown to be higher than the FPC. We can improve this SI by adding wire mesh above the Abp for moving the heat energy in between the Abp and the wire mesh and the heat energy on an Abp for transportation of fluid with the MFR of 0.012 and 0.016 kg s1; see Tables 7.3a and 7.3b, and a lesser SI by rates 162 and 187W m2, respectively; we can recover this loose SI by adding wire mesh above the Abp for moving the heat energy in between 27.92 percent and 42.83 percent, respectively, were the maximum THeff figures measured.
