Supervisory predictive control of residential building heating, ventilation, and air conditioning (HVAC) systems could protect electrical infrastructure, enhance occupants’ thermal comfort, reduce energy costs, and minimize emissions. However, there are few experimental demonstrations, with most of the work focusing on simulation studies. To convin...
Residential electrification - replacing fossil-fueled appliances and vehicles with electric machines - can significantly reduce greenhouse gas emissions and air pollution. However, installing electric appliances or vehicle charging in a residential building can sharply increase its current draws. In older housing, high current draws can jeopardize...
Heat pump water heaters (HPWHs) could significantly reduce energy costs and greenhouse gas emissions from water heating, the second largest energy use in residential buildings. Today, most HPWHs use electric resistance heating elements to maintain comfortable water temperatures even during large water draws. Unfortunately, heating elements signific...
Many simulation studies have suggested that advanced control strategies for heating, ventilation, and air-conditioning (HVAC) equipment in commercial buildings can help reduce energy costs and greenhouse gas emissions. However, despite these potential benefits, adoption of advanced HVAC control remains limited, due in part to a lack of confidence i...
The rapid electrification of residential buildings has created rising concerns about the ability of the power grid to deal with seasonal electric space conditioning peaks. Better control of home heating and cooling systems can help solve this problem. However, unlike other control areas where extensive data are often available, each home presents a...
Electrifying vehicles and residential appliances can significantly reduce greenhouse gas emissions in areas with clean electricity. However, the electrical infrastructure in most older houses, was not designed to accommodate peak current draws from large loads, such as space heating, water heating, and vehicle charging. Upgrading a house's circuit...
Model predictive control of residential air conditioning could reduce energy costs and greenhouse gas emissions while maintaining or improving occupants' thermal comfort. However, most approaches to predictive air conditioning control either do not model indoor humidity or treat it as constant. This simplification stems from challenges with modelin...

I am working on setting up a two-phase simulation in COMSOL involving the electrooxidation of acetone to isopropanol and the subsequent phase change that can occur. Does anyone have experience on custom fuel cell or electrolyzer simulation in COMSOL that do not use the fuel cell module? By fuel cell module I mean the integrated (fc) physics option. Any relevant publications that explain how to couple darcy's law and the Brinkman equation in the cathode are appreciated.
I am trying to model the OCV of an electrochemical reaction where: ACT(g) + 2H+ + 2e- --> IPA(l), at T = 25 Celcius (Standard Temperature) and P = 19.6 KPa (P < Standard Pressure). The phase change occurs due to the low pressure and the differences in saturation properties between these substances. Any help is appreciated.
