Heat Transfer By Steady Laminar Free Convection In Triangular Enclosures

ABSTRACT

Two Dimensional Laminar Free Convection in a fluid contained in a long horizontal right triangular enclosure has been investigated using numerical techniques and an experimental study. The geometry of the enclosure is such that the base is assumed horizontal while the vertical height is adiabatic. Motion in the region is set up by heating the hypotenuse while cooling the horizontal wall.

This model simulates heat transfer problems associated with pitched-roofs with suspended ceilings, roof-type solar stills etc. The systems of equations generated out of the Continuity, Energy and Momentum transport equations have been solved by an iterative procedure and steady-state solutions have been obtained for Height/Base ratios of 0.0625
