“…The impacting air jets solar air heater enclosed by fins in the bottom of the absorber region for noncross flow design has been the subject of an experimental investigation for various configurations [6]. According to a review of the literature and comparison research, solar air thermal collectors with fins transmit heat more quickly than those without fins [7]. N. F. Hussein investigated the thermal efficiency of two counterflow double-pass solar air heater configurations: conventional flat plate absorbers and waterfilled tubular capsules.…”

This paper investigated the thermal performance of a solar air collector with attached rectangular fins both theoretically and experimentally. The effects of mass flow rate (0.015 kg/s to 0.06 kg/s) and fin spacing on thermal performance and temperature rise were investigated using varying solar radiation intensity (500, 600, 700, and 800 W/m2). The results show that, when using a finned absorber instead of a plane absorber, the maximum thermal efficiency of 1.264 times was achieved. Additionally, at a lower mass flow rate of 0.015 kg/s, a maximum increase in temperature rise has been observed to be 1.243 times greater than that of a plane absorber.

“…In addition, the temperature of the thermal output of the parabolic collector at the absorber tube wall increases with rising heat flux, and, it is increased from 350 to 390 K in laminar flow and from 310 to 325 K in a turbulent flow. Kumar et al (2021) presented a comprehensive review of performance analysis of with and without fins SAH. The authors found that the thermal efficiency increases continuously with an increase in fluid mass flow rate, whereas thermohydraulic efficiency increases up to an inception value of fluid mass flow rate, attains a maximum, and then decreases sharply for a given fin spacing and fin height.…”

In this paper, we made a numerical simulation of convective heat transfer in a rectangular section pipe of a air flat plate solar collector using three forms of the absorber plate namely, simple shape, rectangular-shape, and half circle-shape. The flow is considered laminar and stationary, where the heat exchange between the absorber plate and the fluid takes place in useful area. The computer code in fluid dynamics, the fluent, is applied to integrate the governing equations on each control volume. A detailed description of the fluid flow and heat transfer in the rectangular channel was made. Several simulation were carried out in order to determine the influencing parameters allowing better performances of the collector and ensuring a good homogeneity of the temperature at the exit of the channel. The obtained results showed that the lows mass flow rates of the air increase the average outlet temperature. Also, the use of the second configuration of the absorber (rectangular shape) increases the velocity of the air at the downstream of the channel and promotes more the thermal homogeneity at the outlet of the channel.

“…The equilateral triangular tube offers the optimum heat storage and release properties, according to the results. (Kumar et al, 2021) By including different fin shapes on the bottom of the absorber plate in single-pass and double-pass solar thermal collectors, it was shown how to increase thermal performance. the impact of various fin shapes employed by researchers to increase the thermal efficiency of thermal collectors.…”

In a Fresnel-based Concentrated Photovoltaic system, multi junction solar cells suffer from increased PV temperature, resulting in a decrease its electrical efficiency. This study design to investigate the influence of using Water/Al2O3 Nanofluid as cooling fluid on heat transfer enhancement and top surface temperature for multi-junction solar cell in the Fresnel-based Concentrated Photovoltaic thermal CPVt System. The CFD simulation was conducted on mini-channel under the concentrated multi-junction solar cell with using water/Al2O3 Nanofluid and pure water as coolant fluids. The Reynolds number is in the range of 15000-30000 were examined. The average Nusselt numbers augmented through increasing Reynolds numbers. The water/Al2O3 Nanofluid provides highest heat transfer enhancement of 23% compare with water in Fresnel-based CPVt system. The top surface temperature decreases as Nusselt number increases. The Nuavg improves 21% with using of water/Al2O3 Nanofluid at lowest Reynolds number of 15000 and 23% at highest Reynolds number of 30000.The top surface temperature dropped from 337K to 327K at lowest Reynolds number of 15000 with using Water/Al2O3 Nanofluid as cooling fluid and from 323K to 315K at highest Reynolds number of 30000.This study has confirmed that the use of water/Al2O3 Nanofluid has significant influence on the dissipate the heat from Multi-Junction Solar Cell in Fresnel-based CPVt system which led to improve its electrical efficiency.
