Modeling of Flat-Plate Solar Collector Operation in Transient States
Saleh, Ahmad M. M.S.E., Purdue University, May 2012. Modeling Of Flat-Plate Solar Collector Operation in Transient States. Major Professor: Hosni Abu-Mulaweh. Solar energy is becoming an alternative for the limited fossil fuel resources. One of the simplest and most direct applications of this energy is the conversion of solar radiation into heat, which can be used in water heating systems. A c...
متن کاملDesign and Development of Compound Parabolic Concentrating Solar Collector with Flat Plate Absorber
In this research work 2-D CPC (Compound Parabolic Concentrator) with flat plate absorber and two parabolic reflectors is first designed and then fabricated for thermal performance analysis. Here the incident rays, after reflection from the reflector, are not focused at a point but are simply collected on a line of absorber surface. Acrylic sheets are provided to reduce the heat loss. Flat plate...
متن کاملUWB Spiral Antenna with Parabolic Reflector
A cavity-backed spiral antenna with ultra-wide band width is presented. By using a parabolic reflector, the radiation of the antenna becomes uni-directional, and the gain is promoted. The antenna is fed by a coaxial cut-away balun with fan-shaped patch which keeps a wideband impedance matching. The simulated bandwidth for VSWR < 2 covers 0.36 ~ 6.83GHz or bandwidth ratio of 19:1, and the gain a...
متن کاملA-Si FLAT PANEL
Flat Panel Illustration In 2000, a large array A-Si flat panel EPID detector was installed (AL-7) on one of the PRIMUS accelerator at UCSF to allow for a comparison of performance. During the development period of MVCBCT, the introduction in 2004 of a new flat panel (AG-9) better optimized for high energy photons showed a several fold increase in sensitivity, allowing the routine acquisition of...
متن کاملاثر آینۀ ثانویه بر مقدار و توزیع شار ورودی لولۀ جاذب در متمرکزکننده‌های فرنل
Flat reflectors which have lower price compared with parabolic ones are used in Fresnel concentrator. Each Fresnel collector is comprised of a few flat reflectors which are placed parallel to each other near the ground. If effective width of flat reflectors is more than absorber tube diameter, reflected rays will be partly lost, hence low optical efficiency. By installing a secondary reflector ...
