Abstract
In the present paper, a numerical study of mixed convection flow of a three-dimensional building integrated photovoltaic thermal front (BIPV/T) has been investigated. The configuration consists of a cubical system heated by a solar panel partition. The left wall has an inlet damper at the bottom allowing the cold air flotation in a gap between the solar panel and the opposite vertical insulated wall. The finite volume method is used to analyze the dynamic, thermal fields and the heat transfer flow of the system. The results revealed that the heat transfer rate is affected by Reynolds and Nusselt number’s variations.
Highlights
Solar energy is the most promising energy resource on earth[1]
The electrical efficiency of such hybrid system reaches up to 6% and its overall efficiency is about 67.5% [4]. This technology can effectively be integrated into buildings as an architectural element providing heat and electrical power in order to reduce energy consumption[5]–[7]
This paper presents an extension of previous works
Summary
It’s virtually inexhaustible, sustainable and is currently exploited by two major technological approaches: thermal and photovoltaic[2]. The new popular technology combines both methods of energy conversion. The electrical efficiency of such hybrid system reaches up to 6% and its overall efficiency (including recovered heat) is about 67.5% [4]. This technology can effectively be integrated into buildings as an architectural element providing heat and electrical power in order to reduce energy consumption[5]–[7]. A considerable literature has grown up around heat transfer mechanisms through numerical simulations and experimental studies
