The reduction of convective heat output at panel radiators
Result description
The main aim of the research work is to describe temperature and velocity fields above the panel radiator fitted with non-standard (or design) covering grids with various flow cross-section and the subsequent effect at an air flow throughout the room. The effect of flow cross-section and shape of openings of panel radiators covering grids at their heat output was determined experimentally. The other experiment dealt with description of velocity field above the covering grid, using the method of particleimage velocimetry (PIV). The results are presented in a graphic form as a heat output decrease depending on parameters of the covering grid and in the form of velocity vectors placed in two orthogonal planes. Based on experimentally obtained data, the mathematical model will be verified. Then a computer fluid dynamics (CFD) will be used to simulate both temperature and velocity fields above the panel radiator and in the room.
