Advances in PV and PVT cooling technologies: A review

• Cooling methods of PV panels were summarized. • Role of NePCM in cooling the PV panels were discussed. • Parameters affecting the performance of NePCM were illustrated. • The challenges facing the NePCM were given. Phase change materials (PCMs) are one of the promising materials in thermal energy storage (TES) systems, while commonly utilized PCMs have weak thermal conductivity. Therefore, elevating high relatively thermally conductivity for the PCM composites using various nanoparticles with different named the nano-enhanced phase change material (NePCM) is an encouraging solution for regulating the PV temperatures and hence prolonging the lifetime of the utilized photovoltaics. The present paper introduces the cooling methods of PV panels as well as reviews the PV/PCM systems. Additionally, the cooling of photovoltaics based on the NePCM methods are studied showing the preparing methods of the NePCM nanocomposites. The results indicated the dispersion of NPs into the PCMs modifies the thermo-physical properties of PCM like melting temperature, supercooling degree, heat of fusion, viscosity, etc., as well as the mass fraction of NPs affects remarkably the enhanced thermal conductivity (TC) of NePCM nanocomposites. Thus, the NePCMs introduce superior characteristics of heat transfer as a result of intensifying the TC of PCM. Therefore, adding the nanoparticles to the PCM had a noteworthy potential for intensification the thermos-physical properties of PCM so it is a promising choice for TES in solar photovoltaics applications.

Recently, a homogeneously weighted moving average (HWMA) chart has been suggested for the efficient detection of small shifts in the process mean. In this study, we have proposed a new one-sided HWMA chart to effectively detect small changes in the process dispersion. The run-length (RL) profiles like the average RL, the standard deviation RL, and the median RL are used as the performance measures. The RL profile comparisons indicate that the proposed chart has a better performance than its existing counterpart’s charts for detecting small shifts in the process dispersion. An application related to the Dhahran wind farm data is also part of this study.

A New HWMA Dispersion Control Chart with an Application to Wind Farm Data

Although little attention is paid to corrosion study in food processing and production industry, it is highly important to take a critical look at what transpires at the production stages and how these can affect human health due to contamination of the final product. This research employs the design of experiment module of a Minitab software to analyze the corrosion effect of mild steel in fruit juice environment. Coupon method was adopted to calculate the rate of corrosion in orange, pineapple, and cashew fluid for a duration of 25 days with measurement taken at 5-day intervals. The highest corrosion rate of 0.71 mmpy was observed in cashew fluid followed by pineapple fluid, and the least rate of 0.08 mmpy was observed in orange fluid. The generalized model equation was obtained to predict corrosion rate of mild steel in a similar environment. In general, design of experiment offers a better way to analyze corrosion experiment result, and this innovative idea is shown in this work.
