Rethinking Pipe Flow Stability: Insights from a Meshless Global Analysis
Akash Unnikrishnan, Vinod Narayanan
Despite extensive experimental evidence of turbulence in Hagen Poiseuille flow, linear stability analysis has not yet confirmed its instability. One challenge is the singularity in…
Bifurcation in narrow gap spherical Couette flow
Ananthu J. P., Manjul Sharma, Sameen A. +1
Incompressible Navier-Stokes equations in the spherical coordinates are solved using a pseudo-spectral method to simulate the problem of spherical Couette flow. The flow is investi…
High-order meshless global stability analysis of Taylor-Couette flows in complex domains
Akash Unnikrishnan, Vinod Narayanan, Surya Pratap Vanka
Recently, meshless methods have become popular in numerically solving partial differential equations and have been employed to solve equations governing fluid flows, heat transfer,…
