Numerical simulation of buoyancy-driven laminar flow through an air-filled isosceles triangular enclosurewith a differentially heated side walls and an adiabatic bottom wall

Abstract EN

Thermal And Flow Fields Due To Laminar Free Convection In An Isosceles Triangular Enclosure Having Thick Conducting Sidewalls Have Been Investigated Computationally.

Inclined Left And Right Side Walls Are Maintained At Isothermal Hot And Cold Temperatures Respectively While The Bottom Wall Is Considered Adiabatic.

Problem Has Been Analyzed And The Non-Dimensional Governing Equations Are Solved Using Finite Volume Approach And Employing More Nodes At The Fluid–Solid Interface.

Triangular Enclosure Is Assumed To Be Filled With An Air With A Prandtl Number Of 0.7.

Rayleigh Number Varies From 103 To 106 Where The Flow And Thermal Fields Are Computed For Various Rayleigh Numbers.

Consequently, It Was Observed That The Stream Function And Temperature Contours Strongly Change With High Rayleigh Number.

The Streamline And Isotherm Plots And The Variations Of The Average Nusselt Number At The Hot Left And The Cold Right Side Walls Are Also Presented.

The Results Explained A Good Agreement With Another Published Results.
