Venetian blinds are widely used to properly adjust the amount of incoming daylight for energy savings in lighting and cooling and to deal with glare for visual comfort. Two computer tools, Radlink in Adeline and DOE2, have been popularly used for long-term daylighting simulation with venetian...

The reduction of energy consumption for heating and cooling services in the existing building stock is a key challenge for global sustainability today and buildings’ envelopes retrofit is one the main issues. Most of the existing buildings’ envelopes have low levels of insulation, high...

The heat release analysis has proved to be a powerful diagnostic tool for the analysis of the combustion process in spark ignition engines. Still, a fine tuning of the heat transfer correlations embedded in the heat release models is necessary for a correct diagnostic analysis of the pressure...

Methanol and ethanol are promising alternative SI engine fuels. Engine simulation tools could help to unlock the full potential of these fuels. Previous work by the current authors has focused on building submodels to predict the gas dynamics, combustion and knock occurrence in alcohol engines....

A Multi-Approach Evaluation System (MA-ES) is established in this paper providing comprehensive evaluations on Organic Rankine Cycles (ORC) used for waste heat utilization. The MA-ES covers three main aspects of typical ORC performance: basic evaluations of energy distribution and system...

A thorough understanding of the mechanisms of ion crossover through the membranes in vanadium redox flow batteries (VRFBs) is critically important in making improvements to the battery’s efficiency and cycling performance. In this work, we develop a 2-D VRFB model to investigate the mechanisms...

A numerical model has been developed to study the complex thermal behavior of a CO2-filled vertical geothermal borehole consisting of a long copper U-tube embedded in a solid material (grout). The model accounts for combinations of single-phase and two-phase fluid flow which may occur along the...
