A method to extract macroscopic interface data from microscale rough/porous wall flow fields
Vedanth N Kuchibhotla, Sujit Kumar Sahoo, Y. Sudhakar
Performing geometry-resolved simulations of flows over rough and porous walls is highly expensive due to their multiscale characteristics. Effective models that circumvent this dif…
A general pressure equation based method for incompressible two-phase flows
Hormuzd Bodhanwalla, Dheeraj Raghunathan, Y. Sudhakar
We present a fully-explicit, iteration-free, weakly-compressible method to simulate immiscible incompressible two-phase flows. To update pressure, we circumvent the computationally…
Prediction of drag components on rough surfaces using effective models
Sahaj Jain, Y. Sudhakar
Owing to the multiscale nature and the consequent high computational cost associated with simulations of flows over rough surfaces, effective models are being developed as a practi…
Higher order homogenized boundary conditions for flows over rough and porous surfaces
Y. Sudhakar, Ugis Lacis, Simon Pasche +1
We derive a homogenized macroscopic model for fluid flows over ordered homogeneous porous surfaces. The unconfined free-flow is described by the Navier-Stokes equation, and the Dar…
Transfer of mass and momentum at rough and porous surfaces
Uǧis Lācis, Y. Sudhakar, Simon Pasche +1
The surface texture of materials plays a critical role in wettability, turbulence and transport phenomena. In order to design surfaces for these applications, it is desirable to ch…
Online Rotor Resistance Adaptation Of Induction Motor Drive
Yuva sudhakar, P. M. Tiwari
In this paper an adaptive control systems scheme is used to update the rotor resistance of an induction motor drive. Rotor resistance of the induction motor drive is dependent on t…
