Computational 3D Simulations of Fluid Dynamics and Comparisons of Heat Transfer Characteristics of Various Flat-Plate Solar Collectors
This article presents a comparative study of the aerodynamic and thermal behavior of various types of flat-plate solar collectors. The study is based on computational fluid dynamics (CFD) which solves turbulent airflow with different types of baffles. Four models of flat-plate solar collectors were investigated: solar collectors with inclined baffles (SCIB), solar collectors with arched baffles (SCAB), solar collectors with perpendicular baffles (SCPB), and solar collectors with a maze of baffles (SCMB). The reduction in flow passage surface area due to the presence of baffles results in significant increases in airspeed, reaching 254%, 266%, 290%, and 502% of the inlet speed for SCIB, SCAB, SCPB, and SCMB, respectively.
期刊介绍：
Transactions of Mechanical Engineering is to foster the growth of scientific research in all branches of mechanical engineering and its related grounds and to provide a medium by means of which the fruits of these researches may be brought to the attentionof the world’s scientific communities. The journal has the focus on the frontier topics in the theoretical, mathematical, numerical, experimental and scientific developments in mechanical engineering as well
as applications of established techniques to new domains in various mechanical engineering disciplines such as: Solid Mechanics, Kinematics, Dynamics Vibration and Control, Fluids Mechanics, Thermodynamics and Heat Transfer, Energy and Environment, Computational Mechanics, Bio Micro and Nano Mechanics and Design and Materials Engineering & Manufacturing.
The editors will welcome papers from all professors and researchers from universities, research centers,
organizations, companies and industries from all over the world in the hope that this will advance the scientific standards of the journal and provide a channel of communication between Iranian Scholars and their colleague in other parts of the world.
