The Rayleigh-Benard convection in an enclosure with walls of finite thickness

Research output: Contribution to journalArticlepeer-review


Mathematical simulation of transient natural convection in an enclosure having walls of a finite thickness at the presence of a heat source located at the bottom of the cavity has been carried out. Special attention was given to the analysis of the Grashov number (Gr) effect, describing the intensity of a heat source; of the transient factor, defining the formation and development of thermodynamic structures; and also of the heat conductivity ratio. Typical distributions of streamlines and temperature fields have been received. Scales of key parameters (the Grashov number, dimensionless time, the heat conductivity ratio), affecting both local characteristics (streamlines, isotherms) and integral characteristics (the average Nusselt number) of the analyzed process, have been determined.
