The first method used oil direct air natural (ODAN), based on a free convection heat transfer. The second method follows the forced convection principle in an oil blunt air force (ODAF) that requires an air-blower fan to cool the oil. Hence two fans of the same properties were used with an average speed of 6.5 m/s. Both experiments were performed with an inlet oil temperature of (70°C) when the oil flows of (1, 2, 3 l/m). Maximum cooling capacity showed an acceptable improvement when using an oil flow rate of 3 l/m. It was 2620 Watts for the transformer utilizing the ODAF method of cooling. On the other hand, the transformer with ODAN cooling method reached only 1908 Watts.</p> Aymen Al-Tememe, Zaid M. Al-Dulaimi, Hassanain Gh.

However, a small portion of absorbed sunlight will be utilized in an electrical grid, while the remaining is lost in the form of heat. The rise in temperature negatively affects the cell’s efficiency and reduces the cell’s life span. In order to get rid of this side effect, many different cooling techniques were used. This paper is reviewing the existed technologies that are used to reduce the impact of temperature on (PV) performance that aims to achieve the highest efficiency.</p> Sarah Yahya Hattam Al-Maliki, Mahdi Hatf Kadhum Aboaltabooq Copyright (c) 2021 Al-Furat Journal of Innovation in Mechanical and Sustainable Energy Engineering Sat, 14 Aug 2021 00:00:00 +0300 New Design of Cylindrical Solar Still with Hemispherical Dome <p class="AbstractKeywordsJOSA" style="text-indent: 35.45pt;"><span style="font-style: normal;">Under Al-Najaf city weather conditions, cylindrical solar still with a hemispheric dome (CSSHD) was designed, manufactured, and tested. To maximize its absorption, the trough was made of black brass material that pained black with a circular shape (0.13m diameter). The cover is made of glass (0.3m) length, (0.15m) outer diameter, (0.142m) inner diameter, and (0.002m) thickness. Numerous experiments were conducted to observe the behavioral variation inside the still. The experimental study investigated the effects of solar radiation, basin height of (0, 10, 20) cm, and wind speed of CSSHD on the productivity of solar still and temperature distribution inside the still during three months (Dec 2019, Feb and June 2020). The results showed that the maximum productivity is in June at a basin height of 20 cm reaches (6.6) L/m<sup>2</sup>.day. The variation of still output with high resistivity of trough (0,10.20) cm showed that the optimal productivity was achieved over 20cm height on the selected day (1.4, 1.6, and 6.6) L/m<sup>2</sup>.day, respectively.</span></p> Mohammad Abd Al Amir Khadim, Wisam A.
