Sir How to define boundary condition?

[@sujatasonkar7649]

Very helpful video thanks sir

You're welcome

[@abdulmajeed3837]

please make another video for the stability of boundary layer flows like blasius flow by the same method.

[@LaplaceAcademy]

Thank you for your interest in the tutorial and your lovely comment. I will do my best.

[@ritamghosh6970]

Please make a video on Spectral Element methods...my sincere request.

[@abdulmajeed3837]

very amazing. i want to find stability for blasius flow. please help me. i shall be very thankful to you

How can I evaluate the stability from this method? What does the final graphs represent? Thanks for you kindness.

[@LaplaceAcademy]

Hi. 8:45 in this moment the exact condition for stability is mentioned in the video. This is an eigenvalue problem, in which the eigenvalue is a complex number, named lambda. If the real part of lambda is negative, then the flow is stable, and vice versa. Also about the graphs: The region inside the tongue-shaped plot is where the flow is unstable. And the ojtside region is stable. The tongue shape curve is called neutral stability curve on which lambda is equal to zero.
