This study reviews the relevant literature on oil price impacts and then applies both asymptotic and bootstrap distribution techniques to model various oil price shocks and to subsequently evaluate their impacts on key macroeconomic variables in Liberia.First, we find that different oil shock measures yield different effects. Second, asymmetries in oil price exist and can be explained by Liberia's...
This paper applies the real options method to analyse the defer option value and optimal investment timing for solar photovoltaic projects in China. The main purpose of this paper is to examine investment behaviours under different market systems and support schemes. This paper further investigates the interaction of technological progress and support schemes. Four scenarios are designed, and the...
To increase photocatalytic rate and PV (photovoltaic) power output of solar modules, an easy-to-fabricate V-trough (2.34 suns) SOLWAT (Solar Water Purification and Renewable Electricity Generation) system was developed for simultaneous water purification and electricity generation. The PV and photocatalytic performance was analyzed in comparison with a non-concentrating SOLWAT system using Acid Red...
A fin-and-tube evaporator can be used for an ORC (organic Rankine cycle) to collect waste heat of the exhaust gas of an internal combustion engine. In this paper, the thermal-hydraulic characteristics of an ORC evaporator are analyzed using a CFD method. A 3D numerical model is derived from an engineering diagram of the fin-and-tube evaporator, and the boundary conditions are specified according to...
Aiming at the recovery of exhaust energy for a diesel engine, a set of ORC (organic Rankine cycle) system is designed. The characteristics of the exhaust gas under various operating conditions are studied through experiment. Based on experimental results and theoretical calculation, effects of eight kinds of zeotropic mixtures on the performance of ORC system for exhaust energy recovery are discussed...
Selection and evaluation of biofilm carrier represent the two significant ways for improving the anaerobic digesters. This study investigated the performances of the AD (anaerobic digestion) reactors using three types of fibrous biofilm carriers, including the ACF (activated carbon fiber), the PVAF (polyvinyl alcohol fiber) and the GF (glass fiber). The biogas and methane production, pH, COD (chemical...
