What is Development of a Novel Computational Fluid Dynamics-based Model for a Solar Photovoltaic/thermal Collector-assisted Domestic Hot Water System with Sensible Heat Storage about?
This study proposes a novel numerical modelling approach to investigate the dynamic performance of a solar photovoltaic/thermal domestic hot water system. A three-dimensional numerical model of a flat-box solar collector developed in ANSYS-Fluent is coupled with a reduced one-dimensional model of all other system components. Coupling these models allows for a more accurate evaluation of the system’s overall performance as consideration is given to both the spatial variations inside the collectors, and the overall system’s temporal response. The city of Ottawa, Canada is used as the case study location and a monthly comparison is made between scenarios comprising two different working fluids (i.e. air and a water-ethylene glycol solution) and two photovoltaic/thermal collector design alternatives (i.e. with and without fins). To assess the performance of each scenario, the solar fraction, electricity fraction, and utilization factor are computed. Results show that the solar fraction is greater in the air-based system than in the water-based system for all months of the year, and values as high as 90.1% and 84.3% are obtained, respectively. Similarly, the addition of fins to these sy
