This study proposes a novel design for a serpentine tube to develop an efficient photovoltaic-
thermal (PV/T) system. For this purpose, three different hybrid nanofluids and two types of …

Metal foam was adopted for improving inherent low thermal conductivity of traditional
thermal energy storage (TES), which conducted higher solar energy conversion efficiency …

The liquid flow close to the interface has received much attention recently, that is determined
by interfacial slip action. In heat exchange tube, the thermal diffusion in the flowing boundary …

The aim of this study is the numerical analysis of the melting process of the phase change
material (PCM) in a spiral coil. The space between the inner tube and outer shell is filled …

Shell and spiral tube heat exchangers are widely favored in refrigeration and applications
such as heat recovery systems, food processing, and heat storage. Researchers' primary …

Passive solutions in buildings have recently been rediscovered because they allow the
rational use of solar radiation, which promotes energy savings. Thermal energy gained from …

Photovoltaic/thermal systems are one of the most efficient types of solar collectors because
they absorb solar radiation and generate electricity and heat simultaneously. For the first …

To address the non-constant heat sources and fluctuating user heat loads of renewable
energy utilization, ultrasonic-assisted solid-liquid phase change technology with a faster …

Heat transfer surface of heat exchange devices often suffers from severe corrosion, and their
corrosion behavior is dramatically influenced by both surface temperature and heat flow. In …

In this research, a novel solar latent heat thermal energy storage (LHTES) system, including
the cylindrical enclosures filled with a phase change material (PCM), is proposed, which can …
