Impact of Sahelian Climate Variables on Solar Photovoltaic Output

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Solar photovoltaic (PV) energy is a critical pathway for advancing the energy transition in the Sahel. However, PV module performance in this region is strongly constrained by extreme climatic conditions. This study investigates the effects of (1) wind speed, (2) relative humidity, (3) temperature, (4) dust deposition, and (5) solar irradiance

Erosion-corrosion mechanism and comparison of erosion-corrosion performance of API steels

Wear, 2017
Abstract During the transportation of oil and gas, pipes are exposed to flowing corrosive environment which causes erosion-corrosion. The high degradation rates attributed to this mechanism can create increased challenges to project economy and operation where material integrity, accurate erosion-corrosion rate prediction and long term performance ...

An approach to modelling erosion-corrosion of alloys using erosion-corrosion maps

Corrosion Science, 1993
A model has been developed to establish the boundaries on erosion-corrosion maps, where increases in erosion and corrosion are represented by increases in velocity and temperature respectively. The maps show the transitions through the regimes as functions of the main erosion-corrosion variables.
