In the present study, two indirect type solar dryers were designed, fabricated and
experimentally investigated, one is equipped with a conventional flat plate collector, and the …

Under fluctuating solar radiation, attaining higher air temperatures for an extended period
using solar air heaters (SAH) is challenging. The current study deals with the heat transfer …

Solar air heaters generally operate at constant mass flow rates achieved with constant fan
speed. This situation causes continuous energy consumption in solar air heater (SAH) …

The roughness on the absorber surface can increase the performance of a triangular solar
air heater. This paper reveals a comparative study of smooth and rough absorber surfaces …

The objective of this study is to investigate the Nusselt number and friction characteristics of
rectangular channel solar air heater (SAH) ducts roughened with staggered V-shaped ribs …

Present work reports the findings of experimental investigation performed outdoors in real
time conditions on a novel roughness geometry frustrum roughened solar air heater. The …

This research aims to carry out an experimental investigation into the performance of a solar
air heater using phase change materials in combination with V-corrugated absorber plates …

The use of solar energy for drying is considered one of the most environmentally friendly
ways to reduce dependence on fossil fuels. The purpose of this experimental study is to …

The solar air heater (SAH) is the main component of solar dryers that supplies hot air to the
drying chamber. Therefore, its optimization is necessary to improve the efficiency of solar …

The main objective of this research was to create two different configurations of a flat-plate
solar air heater, namely, Conventional-Case A and Modified-Case B, and develop a three …
