Identification Of Rayleigh-Benard Convection On Physical Model Of Electric Furnace

The released electric energy in the melting tank, the distribution of temperatures in the glass melt and by them generated the flow influences a quality of the manufactured glass melt especially their homogeneity. Between those place where the energy releases and where the energy consumes generates natural convection, called Rayleigh-Benard convection. This type of convective flow is forming by the volumetric releasing of energy and this flow is also present in electric glass melting furnaces. In the melting tank of the furnace is released energy transported to the colder areas for heating and the melting of the batch. Experiments of the physical model were carried out with cooling the surface and heating the room below it.
