Thermal solar collector considers one of the main devices employed to transform energy into thermal and can be classified three types named Evacuated tube (ETC), flat plate (FPC), compound parabolic (CPC) collector. In this study, where it was taken evacuated collectors different geometries inner pipe diameter were proposed combined with type phase change materials (PCM) evaluate their performa...

The current study presents the concept of a stand-alone solar organic Rankine cycle (ORC) water pumping system for rural Nepalese areas. Experimental results for this technology are presented based on a prototype. The economic viability of the system was assessed based on solar radiation data of different Nepalese geographic locations. The mechanical power produced by the solar ORC is coupled w...

Abstract In this paper a new model has demonstrated that it operates in moderate performance scale to generate hot water. its early stage, the preliminary model, which built with double pass water tube inside evacuated tube, was investigated experimentally. The tested room under different operation conditions terms of solar radiation 300, 400, 500 and 600 W/m 2 mass flow rates 0.00305 0.0083kg/...

In this research, a practical study and appraisal of the thermal performance for solar collector with vacuum tube has conducted Two types nanomaterials (aluminum aluminum oxide) have added to distilled water nanoparticles diameters 30 nm 50 respectively. The were used in three several concentrations flow rates which as working fluid evacuated (ETSC) order increase efficiency beneficial gain. An...

Today, Evacuated-Tube transport (ETT) systems, also referred to as hyperloops , are becoming ever more famous. They consist of a ground-based network enclosed within tube in which the atmosphere can be controlled. If air inside is evacuated, low-pressure environment created and aerodynamic resi...
