Natural convection in enclosures with partial partitions

摘要

Laminar and turbulent natural convection in enclosures with partial partitions has been stud- ied by a numerical method. Vertical boundaries were isothermal and horizontal boundaries were adiabatic. Two dimensional equations of conservation of mass, momentum and energy, with the Boussinesq approximation are solved using the Simpler method. Various geometrical parameters were: aspect ratio A=0.3 to 0.4, partition position D=0.5-0.6, height of the par- titions C=D=0 to 0.15. The Rayleigh number was varied from 10~4 to 10~11.
