Paper Title: Passive Cooling on the Performance of Photovoltaic Solar Panels Operating in Extremely Hot Weather Mohammad Zuhour, Osama M. Ibrahim and Nawaf Aljuwayhel, Kuwait University, Kuwait Abstract The peak power output of Photovoltaic (PV) solar panels is typically rated at 25°C, but in hot weather, their operating temperature rises significantly, reducing energy efficiency and power output. This study investigates a passive air convection cooling method to enhance PV panel performance. It examines the impact of adding fins for improved convective heat transfer on the efficiency and power production of PV polycrystalline solar panels in high-temperature environments. Numerical evaluations using one- dimensional thermal models were conducted to predict the panel's hourly average temperature, efficiency, and power output with and without fins. Without fins, the panel had a yearly average temperature of 35°C, efficiency of 15.0%, and total annual power output of 340 kWh/m². Simu...

Paper Title Enhancements to the European Pressure Vessel Codes: A Focus on Conical Components Under Internal Pressure Abstract This paper presents an analysis of conical components in pressure vessels emphasizing their significance when utilized to transition between different diameters or slopes. It aims to propose enhancements to the European Pressure Vessel Codes concerning conical components under internal pressure focused on improving safety, reliability, and compliance with industry regulations. The influence of cone apex angles, shell geometries and design pressure on cone plate thickness calculations is presented. Cylinder diameters between 1000 and 2500 mm and cone angles between 30° and 60° are inputs used to quantify the difference in cone thickness for a design pressure between 10 and 200 barg. The proposed method leads to increased cone thickness compared to AD2000 up to 2.2 mm for the selected range of applications resulting in safer pressure vessel design. Moreover, the ...
