“…Considering the results, the study of low flows rates seemed necessary to find the maximum efficiency that could be reached with the impingement design of minimum crossflow tested, as well as the possibility that the design of zero crossflow could provide positive values of variation in the overall efficiency. The efficiency of the system could also be improved using air jet impingement plate optimization algorithms such as the one developed by Martínez-Filgueira et al [34]. This multi-objective algorithm could determine the optimum nozzle number, diameter, and other interest parameters, depending on the requirements.…”

The photovoltaic cell temperature is a key factor in solar energy harvesting. Solar radiation raises temperature on the cell, lowering its peak efficiency. Air jet impingement is a high heat transfer rate system and has been previously used to cool the back surface of photovoltaic modules and cells. In this work, an experimental comparison of the cooling performance of two different air jet impingement crossflow schemes was performed. Crossflow is defined as the air mass interacting with a certain jet modifying its movement. This leads to a change in its heat exchange capabilities and is related with the inlet-outlet arrangement of the fluid. In this work, zero and minimum crossflow schemes were compared. The main contribution of this work considered the consumption of the flow supplying devices to determine the most suitable system. The best configuration increased the net power output of the cell by 6.60%. These results show that air impingement cooling can play a role in increasing photovoltaic profitability. In terms of uniformity, on small impingement plates with a low number of nozzles, the advantages expected from the zero crossflow configuration did not stand out.

“…Because the product temperature might rise quickly, dry moisture content should be considered in this system. Studies have shown that air impingement systems can cause localized hot and cold spots on a food surface (Martínez-Filgueira et al, 2019). The sample temperature distribution image of these hot- cold spots, which are more common in foods with a large surface area, can be seen in Figure 5.…”

“…where ρ is density, V is velocity, μ is dynamic viscosity, and D is diameter, respectively. Roughness of the surface affects the roughness Reynolds number, which in turn affects the properties of the boundary layer (Martínez-Filgueira et al, 2019). Heat transfer measurements have been studied in several studies of air impingement jets (Donaldson & Snedeker, 1971).…”

“…On the other hand, the disadvantage of the existence of cold or hot points and superheated food surfaces are important, and studies regarding the food quality should be carried out. Another disadvantage of very high initial costs is also important, but short processing times and the use of moderate air temperatures lead to saving in energy (Martínez‐Filgueira et al., 2019).…”

Air impingement method has been widely used in a variety of industrial applications, such as textile and paper drying, turbine cooling, and glass quenching, because it is an efficient technology with high heat and mass transfer rates. This technology has received increasing interest in the field of food processing over the last two decades, such as drying, baking, blanching, freezing, and thawing. In a food processing equipment using air impingement, jets of high‐velocity air (with speeds of 10–50 m/s) are directed at a food product. The performance of the system is influenced by several critical elements, including jet velocity, nozzle array diameter and layout, jet distance, and boundary layer characteristics. The use of computational fluid dynamics, an emerging tool, has been shown to be valuable in the analysis of fluid flow and heat and mass transfer in jet impingement systems. The physical properties of impinging jets, such as turbulent mixing in the free jet zone, stagnation, boundary layer formation, recirculation, and their interactions with food products in terms of heat and mass transfer, have been discussed in this article. The benefits and disadvantages of air jet impingement technology in different food processing applications together with potential trends for improving impingement technology performance were identified and discussed. This review not only contributes to a better understanding of the research status of impingement technology on food processing but also triggers new research opportunities in this field in order to provide more healthy and nutritious food in a more sustainable way to the world's growing population.

Battery Sizing Optimization in Power Smoothing Applications

The main objective of this work was to determine the worth of installing an electrical battery in order to reduce peak power consumption. The importance of this question resides in the expensive terms of energy bills when using the maximum power level. If maximum power consumption decreases, it affects not only the revenues of maximum power level bills, but also results in important reductions at the source of the power. This way, the power of the transformer decreases, and other electrical elements can be removed from electrical installations. The authors studied the Spanish electrical system, and a particle swarm optimization (PSO) algorithm was used to model battery sizing in peak power smoothing applications for an electrical consumption point. This study proves that, despite not being entirely profitable at present due to current kWh prices, implanting a battery will definitely be an option to consider in the future when these prices come down.
