“…However, it was determined that the amount of nanofluid used has an effect on productivity. Sharma et al [60] investigated the effects of nanofluid use on thermal performance in an FPSC. Thermophysical parameters of the nanofluid were measured at different concentrations using a particle size of 30 nm.…”

The importance of using solar energy, one of the renewable energy sources, has started to be understood more recently. The negative environmental effects and limited amounts of fossil fuels have led to increased demand for renewable energy sources worldwide and the production of various models and devices has accelerated to take advantage of solar energy, which is the basis of all energy sources. Using solar collectors as a way to benefit from solar energy has been used for many years. Although solar collectors are generally divided into 4 types as flat plate (FPSC), evacuated tube (ETSC), parabolic (PSC) and heat pipe (HPSC), these types can also be divided into separate types with many different features. The most commonly used solar collector type in the world is Flat Plate Solar Collector. The most important reasons for this are being cheap, easily produced and applied in various ways. Yet, the thermal productivity of FPSCs decreases below 40% in non-ideal climate conditions with low surrounding temperature. The existence of such disadvantages of FPSCs led to the production of Evacuated Tube Solar Collectors. With the advancing technology, the utilization of heat pipes in collectors has come to the agenda and as a result of the studies conducted, it has been determined that the use of heat pipe improves efficiency. In addition, the use of nanofluids in solar collectors and heat pipes has become quite common, and many studies have been carried out especially on this subject recently. The primary objective is always to improve the performance of the system and achieve efficiency. In this way, solar energy will be used in the most effective way and world energy supply demand will be met by using renewable resources.

“…The experimental results showed an increase in the thermal efficiency of flat plate solar collector when using nano-fluid compared to water as follows: 4.81% and 6.57% at a concentration of 0.05% and 0.1%, respectively. Shubham Sharma et al (2020) [15] they presented an experimental study to evaluate a flat plate solar collector performance. They used water and copper oxide in water (CuO/water) with a range of volume concentrations (0.25%-2%) as working fluids.…”

Solar energy is one of the most important types of renewable energy and is characterized by its availability, especially in Iraq. It can be used in many applications, including supply thermal energy by solar collectors. Improving the thermal efficiency of solar collector leads to an increase in the thermal energy supplied. Using a nano-fluid instead of base fluid (water is often used) as a working fluid is a method many used to increase the thermal efficiency of solar collectors. In this article, the latest research that used nano-fluid as a working fluid in evaluating the thermal efficiency of solar collector, type flat plate was reviewed. The thermal efficiency improvement of flat plate solar collector was reviewed based on the type of nanoparticles (metal oxides, semiconductors oxides, carbon compounds) used in the base fluid and comparison was made between these nanoparticles under the same conditions. Moreover, the effect of varying the concentration of nanoparticles in the base fluid and changing the working fluid flow rate on the thermal efficiency of flat plate solar collector was also reviewed. The results of the review showed that nano-fluids containing carbon compounds are better than other nano-fluids and that copper oxide is better than the rest of the metal oxides used in improving the thermal efficiency of flat plate solar collectors.

“…Solar collectors convert the incident solar radiation into heat and then transfer the same to a working fluid flowing through an array of tubes or channels (Figure 1). As the type of working fluid used affects the thermal efficiency of solar collectors, different types of working fluids, especially nanofluids, have been explored by researchers in recent times 1–8 . Higher thermal efficiency is reported in the literature for solar collectors using nanofluids as compared to their base fluids.…”

Effect of magnetic field on the thermal performance of a ferrofluid‐based solar flat plate collector

et al. 2022

In this paper, the effectiveness of ferrofluid as a working fluid for solar flat plate collectors (FPCs) is studied. A mini‐ferrofluid‐based solar FPC is designed and tested under laboratory conditions. The thermal performance of the designed solar FPC is evaluated under different conditions and it is observed that it provides higher efficiency for the case of ferrofluid in the presence of a magnetic field. The thermal efficiency is observed to increase by 54% for ferrofluid in presence of a magnetic field as compared to no magnetic field. The thermal efficiency is observed to increase further with the increase in the magnetic field. The increase in thermal efficiency is attributed to the combined effects of higher thermal conductivity and magnetohydrodynamics of ferrofluid, which result in higher convective heat transfer from the riser tube walls into ferrofluid. The higher heat transfer for ferrofluid with a magnetic field is established by calculating the Nusselt number numerically using COMSOL. Simulation results show an increase in Nusselt number for ferrofluid with magnetic field and hence higher thermal efficiency for the solar FPC. The designed FPC provides simple modifications to conventional FPCs to use ferrofluid with magnetic field for higher thermal efficiencies.
