In this paper we propose to approximate a large parabolic surface with small flat mirrors. This idea was realized for the first time in 1982 in Australia [1] using 2300 rectangular flat mirrors of 100x100 mm2. The concentration rate of 970 suns was obtained.

However, mi-wave IR rrors for long wavelengths use coatings of gold. Bare metals provide high reflectance but they are susceptible to chemical attack andCalculate the Reflected Hourly Solar Radiation by Mirror [19]. In solar power plants, steam is produced by concentrating the solar radiations through mirrors that are in the shape of a flat, dish or parabolic trough [20]. A high concentration of solar radiation is required when solar concentrators that contain reflective mirrors are used [21].

The parabolic reflector transforms an incoming plane wave travelling along the axis into a spherical wave
Parabolic Trough - Angle (Theory) : Solar energy Labs
Collector Flow Rate: The collector flow rate should be high so that efficiency does not go down from high collector temperatures. On the other hand, flow rate should not be too high, in order to maintain the energy transfer demands within acceptable range. This is the mass flow rate rewritten as a area flux, measured in kg/m^2 hr.Receiver Tube - an overview ScienceDirect Topics Parabolic trough solar power generation (Fig. 1.9) is a technology that concentrates solar irradiation in the receiver tube mounted at the focal line of the paraboloid through linear parabolic mirrors that track the movement of the sun and thermal the heat transfer liquid for power generation.

Why Choose A Parabolic Trough for Solar Thermal Power
May 04, 2011 The reflective part of parabolic troughs can be made out of many varieties of material. Since I was cost-concious on a small-scale model, I stuck with reflective mirror-like poster board found at my local Michaels. However, That was almost $5 for 6 square feet (2 sq. m) and would not last rain, let alone many other elements.Why do we use mirror in solar cooker? Restaurantnorman Aug 19, 2020 Why are parabolic mirrors used as reflectors in solar heaters and cookers? Parabolic solar cookers use a parabolic-shaped reflector to direct sunlight to a small area in order to generate heat for cooking. They are able to reach high temperatures, 350 C (662 F) or higher, which allows them to be used for grilling and frying.
