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…
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,…
Taylor-Couette flow in an elliptical enclosure generated by an inner rotating circular cylinder
Akash Unnikrishnan, Surya Pratap Vanka, Vinod Narayanan
Taylor-Couette flow between rotating cylinders is a classical problem in fluid mechanics and has been extensively studied in the case of two concentric circular cylinders. There ha…
Shear-Driven Flow in an Elliptical Enclosure Generated by an Inner Rotating Circular Cylinder
Akash Unnikrishnan, Shantanu Shahane, Vinod Narayan +1
Shear-driven flow between a rotating cylinder and a stationary elliptical enclosure is studied in this paper. Two-dimensional time-dependent Navier Stokes equations are solved usin…
