A new open-loop heat flux control technique has been developed to conduct transient thermal testing of thick, thermallyconductive aerospace structures. This technique uses calibration of the radiant heater system power level as a function of heat flux, predicted aerodynamic heat flux, and the properties of an instrumented test article. An iterative process was used to generate open-loop heater ...

The main aim of this study was to develop an integrated solar-tracking system maximize the efficiency solar heaters manufactured from recyclable aluminum cans (RAC) for optimum drying apple slices. results revealed that thermal air heater incorporated with a tracking unit significantly improved by about 45% compared conventional fixed at all tested flow rates. highest 87.1% equipped achieved ra...

Solar hot water tanks (SHWT) based on a latent heat storage system are gaining momentum for their integration into solar heater collectors. They can efficiently store daytime thermal energy and shift on-peak period loads to off-peak periods. However, performance is generally limited by the tank configuration, design of system, selection appropriate phase change material (PCM). This work present...

Thermo-hydraulic performance of a Double Pass Parallel Flow Solar Air Heater (DPPFSAH) roughened with perforated multi-V ribs has been studied experimentally in prior study and the effect variation open area ratio change relative roughness width analysed reported. The current work builds upon aforementioned earlier by discussing detail methodology various steps involved development correlation ...

Solar power is often regarded as one of the most promising forms alternative energy since it both sustainable and renewable. It difficult to utilize benefit from solar in residential industrial applications because intermittent nature its supply. A solar-based water heating system efficient for using thermal conversion, simplest successful method turning into energy. In this research, performan...

A hybrid photovoltaic solar assisted loop heat pipe/heat pump (PV-SALHP/HP) water heater system has been developed and numerically studied. The system is the combination of loop heat pipe (LHP) mode and heat pump (HP) mode, and the two modes can be run separately or compositely according to the weather conditions. The performances of independent heat pump (HP) mode and hybrid loop heat pipe/hea...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

Due to the depletion of fossil fuel reserves, it is now more important than ever explore and use alternate forms energy. “Solar energy a promising long-term solution that can meet world's needs. essential we energy-related solutions as soon possible. Solar solution. Artificially roughened solar air heaters perform better smooth ones under same operating conditions. However, artificial roughness...
