Abstract
Most Of The Stability Problems In Fluid Mechanics May Be Reduced To Algebraic Eigenvalue Problems By Certain Simplifying Assumptions. The Problem Still Poses A Difficu'lity In Solving, Due To The Non-Linearity Of The Eigenvalue Appearing In The Equation . An Algorithm To Solve This Type Of Problem Is Presented And Applied To A Specific Problem, Namely The Rayleigh- Benard Thermal Stability Problem.The Differential Equations Governing The Phenomenon Are Reduced To Algebraic Form Using The Chebyshev-Gauss-Lobatto Collocation Method. On Applying Boundary Conditions (Free-Free),An Over-Determined System Of Equations Is Obtained .With Suitable Matrix Manipulation, This May Be Reduced To A General Eigenvalue Problem . The Resulting Algebraic Form Of The Generalised Eigenvalue Problem Is Solved Using The QZ Algorithm
