In this paper, three mathematical models to predict the air collector temperature are reviewed and analyzed. These were drawn from 30 publications between 1980 2022. The include lumped model (model 1), a one-dimensional (1D) steady 2), 1D unsteady 3). established based on energy balance of heat exchanger surfaces airflow. Solution techniques for presented using system linear equations, numerica...

This paper presents the thermo-hydraulic performance of small conical ribs on absorber plate a solar energy air heater (SAH) using exergy analysis. Application protrusion is an attractive solution for enhancing thermal SAH. However, these are also responsible high friction losses and increased fan power consumption caused by turbulent flow. To optimize rib design, it vital to consider both hydr...

This work is an effort to investigate the thermal performance of a V-Corrugated Solar Air Heater (SAH), which intended for supplying heating office space having floor area 84 m2. Thermal investigation has been carried out both theoretically and experimentally. SAHs have not investigated in offices, hence this study aims contribute by proposing promoting them purpose. The load evaluated Energy P...

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...
